test-http-exit-delay has a flaky history. Examination of the bug it was
written to find suggests that the test should be removed.
* The test is trying to find a delay of up to 1 second, but the delay
may also be much smaller than that. So the test will not catch the bug
all the time. It is therefore flaky when the bug exists.
* Experience has shown that the test is flaky as well when the bug is
absent in the code because it can sometimes take slower devices (such as
the Raspberry Pi devices that we have in continuous integration) more
than the allowed one second to run. Increasing the timeout for those
devices will make the test pass but will also mean that the test isn't
really testing anything because the delay it is trying to catch was a
delay of up to one second.
I don't think this is an appropriate test to run once on CI. If there is
to be a test for the issue in question, it should be a benchmark test
that is run a large number of times. We don't really have such tests in
CI yet
I would argue that this test is actively a problem. It does not reliably
catch the issue it is supposed to catch, nor can it likely be made to do
so. (To do so would likely require converting it to a benchmarking test
as previously described. We don't run those in CI, at least not at this
time.)
Because this test will have both false positives and false negatives,
especially on the slower devices, it contributes to a culture of
dismissing failed tests. It does not reliably identify an issue nor does
it reliably pass on a working code base. This test should be removed.

Previously, test-cluster-disconnect-suicide-race had two issues:
* Magic numbers: How many times to spawn a worker was determined through
empirical experimentation. This means that as new platforms and new
CPU/RAM configurations are tested, the magic numbers require more
and more refinement. This brings us to...
* Non-determinism: The test seems to fail all the time when the bug
it tests for is present, but it's really a judgment based on sampling.
"Oh, with 8 workers per CPU, it fails about 80% of the time. Let's try
16..."
This revised version of the test takes a different approach. The fix
for the bug that the test was written for means that the disconnect
event will fire on a subsequent tick. So we check for that and the test
still fails when the fix is not in the code base and succeeds when it
is.
Advantages of this approach include:
* The test runs much faster.
* The test should be reliable on any new platform regardless of CPU and

Reduce the number of stat() system calls that require() makes by caching

To avoid unbounded growth without implementing a LRU cache, scope the
cache to the lifetime of the first call to require(). Recursive calls
(i.e. require() calls in the included code) transparently profit from
the cache.
The benchmarked application is the loopback-sample-app[0] and it sees
the number of stat calls at start-up go down by 40%, from 4736 to 2810.

suicide message from the worker if the disconnection has been
initiated in the master.

It avoids the creation of unnecessary handles. This issue is causing
intermitent failures in `test-cluster-disconnect-race` on `FreeBSD`
and `OS X`.
The problem is that the `worker2.disconnect` is being called on the
master before the `queryServer` is handled, causing the worker to
be deleted, then the Server handle is created afterwards. Later on,
when `removeWorker` is called from the `exit` handler, there are no
workers left, but one handle, thus the `AssertionError`.
Add a new `test/sequential/test-cluster-disconnect-leak` based on
`test-cluster-disconnect-race` that creates lots of workers and fails
consistently without this patch.

consume enough resources to slow this test down, so don't check the time
constraints (beyond the generous timeout that the test is given by
test.py in the first place, of course).
If we want to do benchmark/performance tests, we should keep them
separate from pure functionality tests. The time check may have been a
remnant of the distant past when Node.js was much slower. It predates
