Formerly spawn errors would be reported as a message printed to the
process' stderr, to match unix behaviour. Unix has now been fixed to
be more sensible, so this hack can now be removed.
This also fixes a race condition that could occur when the user closes
a process handle before the exit callback has been made.
uv_set_process_title() was susceptible to a format string vulnerability:
$ node -e 'process.title = Array(42).join("%s")'
Segmentation fault: 11 (core dumped)
The fix is trivial - call setproctitle("%s", s) instead of setproctitle(s) -
but valgrind complains loudly about reads from and writes to uninitialized
memory in libc. It's not a libuv bug because the test case below triggers the
same warnings:
#include <sys/types.h>
#include <unistd.h>
int main(void)
{
setproctitle("%s", "test");
return 0;
}
That's why this commit replaces setproctitle() with sysctl(KERN_PROC_ARGS).
This commit reapplies commit a9f6f06, which got reverted in 69a6afe. The revert
turned out to be unnecessary.
It's making node.js crash when run as root. Backtrace:

There were too many errors in this commits; it totally broke on
Windows. Besides, when the moon is dark, the cleanup code could delete
some random files from my hard drive.
This reverts commit 7573f4a4c4.
Failed tests would leave behind extra files, and some tests weren't cleaning up
properly in the first place - this adds a cleanup_watch_dir() helper method to
make all the fs-event tests more consistent.
* the callback gets called only once on error, not repeatedly...
* ...unless the error reason changes from e.g. UV_ENOENT to UV_EACCES
* the callback receives pointers to uv_statbuf_t objects so it can inspect what
changed
Demonstrates temporary event loop stall with uv-unix. The issue is that pending
requests aren't processed until the next event (I/O, timeout, etc.) happens.
See #446, #447 and #448.
