How do you get -9 and -15? Exit status is supposed to be between 0 and
127. With bash, 128+N is also used for processes that terminate on a
signal. At the python level, subprocess.wait() uses negative numbers for
signal-terminated processes. And 9 is SIGKILL and 15 is SIGTERM.

My guess is that your script hits a limit, e.g., number of open files,
or stack-size, or... But of course it's only a guess.
