From: Michal Privoznik <mpriv...@redhat.com>
The aim of virProcessAbort() is to reap a child process. It does
so by waitpid()-ing and possibly sending SIGTERM/SIGKILL to the
child process (and waitpid()-ing again). Nevertheless, if
everything fails a debug message is printed. But the message
mentions only the PID and not errno (set by previous waitpid())
which may be useful. For instance when virProcessAbort() is
called over a PID that's not our child:
failed to reap child 16325, abandoning it: No child processes
