[PATCH] Harden os.system
From: Bryan O'Sullivan <bos@serpentine.com>
Add util.system function. This is similar to os.system, but will
either succeed (if the process finishes with a zero exit code) or raise
a util.CommandError (if the process exits uncleanly or is killed by
a signal).
Add util.explain_exit function. This tends to be ubiquitous in code
that calls other processes, and must describe what has gone wrong.
Change some uses of os.system over to util.system.
