Ben Noordhuis	506c7fd40b	test: fix infinite spawn cycle in stdio test Fix parallel/test-stdio-closed introduced in commit `b5f25a9` ("src: ensure that file descriptors 0-2 are valid") to not keep spawning child processes ad infinitum. The test spawns itself as a child process but a missing return statement made the child process spawn itself again, and again, and again. It went unnoticed for some time because the child process exits almost immediately afterwards, i.e. it didn't fill up the process table. The observable effect was an iojs process that was quietly consuming CPU cyles in the background with a PID that was constantly changing.

test: fix infinite spawn cycle in stdio test

Fix parallel/test-stdio-closed introduced in commit b5f25a9 ("src:
ensure that file descriptors 0-2 are valid") to not keep spawning
child processes ad infinitum.

The test spawns itself as a child process but a missing return statement
made the child process spawn itself again, and again, and again.

It went unnoticed for some time because the child process exits almost
immediately afterwards, i.e. it didn't fill up the process table.  The
observable effect was an iojs process that was quietly consuming CPU
cyles in the background with a PID that was constantly changing.

src: ensure that file descriptors 0-2 are valid

Check that stdin, stdout and stderr map to open file descriptors and
remap them to /dev/null if that isn't the case.  Protects against
information leaks or worse when io.js is started with closed stdio
file descriptors.
