[Qemu-devel] [PULL 0/3] qtest: avoid pidfile and QEMU process leaks

[Stefan Hajnoczi]

Reviewed by Paolo and Markus.  Here is the pull request.

v2:
 * Don't call qtest_end() from SIGABRT handler to avoid reentrancy [Paolo]
 * Use sigemptyset() to avoid assumption about signal mask [Markus]
 * if (fd != -1) close(fd) is no longer necessary [Markus]

This series prevents the following qtest issues:

1. Leaking the pidfile if QEMU startup fails, as discovered by Andreas Färber.
2. Leaking the QEMU process when a test case aborts.

Applying this series should make buildbots and manual "make check" users have a
more pleasant and less leaky experience :).
