See, that's odd.  Twelve lines before that, a child process *was*
started, as logged by the debug message.  Even if the subprocess exited
before this line, there ought to have been a zombie process with the
exit status for waitpid() to read.  So I don't see how this could ever
happen.  I've added code to check for this in the latest trunk, though.
Still, the question is: Where did the child process go?

Yes, the exception causes the checking to stop altogether (fixed in
trunk).

This, too, is odd, since we check and log any errors when saving the
pickle file.
