Read the docco for waitpid(). You can get back information on whether the
program exited normally or not. That should be what you're looking for.

Python has the function for this, such as os.WIFEXITED(status)

Regarding pipes and popen2.py and whatnot... we can definitely fix up the
run_svn() command to Do The Right Thing.

On Windows, there is a "win32popenmodule" (or somesuch name). It provides
much of the same pipe semantics, so we could use that to spawn/run an SVN
client.
