Slowness being somewhat subjective but determined by running the
test suite a few times and picking off everything that consistently
clocks in at 2 seconds or more.
Honorable mention for simple/test-tls-server-large-request, it often
runs for 10 (!) seconds or more.
When developer calls setBreakpoint with an unknown script name,
we convert the script name into regular expression matching all
paths ending with given name (name can be a relative path too).
To create such breakpoint in V8, we use type `scriptRegEx`
instead of `scriptId` for `setbreakpoint` request.
To restore such breakpoint, we save the original script name
send by the user. We use this original name to set (restore)
breakpoint in the new child process.
This is a back-port of commit 5db936d from the master branch.

Fixed a bug in debugger repl where `restart` command did not work
when a custom debug port was specified via command-line option
--port={number}.
File test/simple/helper-debugger-repl.js was extracted
from test/simple/test-debugger-repl.js

This makes the output of simple/test-debugger-repl and
simle/test-debugger-repl-utf8 mirror an actual debugger session, so it's
a bit easier to reason about.
Also, it uses the same code for both, and fixes it so that it doesn't
leave zombie processes lying around when it crashes.
Run 1000 times without any failures or zombies.
If the NODE_DEBUGGER_TIMEOUT environment variable is set, then use
that as the number of ms to wait for the debugger to start.
This is primarily to work around a race condition that almost never
happens in real usage with the debugger, but happens EVERY FRACKING
TIME when the debugger tests run as part of 'make test'.
The 'Can't backtrace now' message takes over 10 seconds to return.
That's too much time to have to wait for a test, and when it times
out, it was causing an orphaned node process.
This cleans up the node process, and also removes the test that's
timing out, so that the case is hit less often.
Todo: Make the backtrace message come back faster.
simple/test-debugger-repl has a tendency to fail and leave behind a stray
process that listens on common.PORT, making later tests fail with EADDRINUSE.
`process.debug_port` is useful for changing debugger port in runtime,
before starting it (via SIGUSR1).
Using `--port=` argument for debugger repl, tests will run debugger
server on a `common.PORT` (as it usually does for any other servers).
`process._debugEnd()` stops debugger and its server.
* debugger: implemented process._debugEnd(), `node debug --port=5858 app.js`
* test: start debugger repl on common.PORT
* fixes#2613
* fixes#2614
It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh
the potential stability issues and intrusive changes to the code base that
first-class support for isolates requires.
Hence, this commit backs out all isolates-related changes.
Good bye, isolates. We hardly knew ye.
* remove useless clearline call at Interface start
* silence after .handleBreak()
* output '\b' if this.stdout is not a tty (debugger)
* add '\b' checks for clearline (test)
* Don't buffer command, before it's execution (repl)
* `quit` command, custom streams for .start, stubbed out test, disable
history repeation for non-tty (debugger)
