Due to presumed bugs in an underlying library over which I have no control,
I'm considering a restart in the wee hours of the morning. The basic
fork/exec dance is not a problem, but how do I discover all the open file
descriptors in the new child process to make sure they get closed? Do I
simply start at fd 3 and call os.close() on everything up to some largish
fd number? Some of these file descriptors will have been opened by stuff
well below the Python level, so I don't know them a priori.

Thx,

Skip
