If any processes have a file open when it's removed, the file remains
around until that process exits.  A really handy way to use file-system
storage but make sure it's cleaned up if your process dies for any reason
is:

   fp = open('/tmp/mytmpfile', 'r+')
   unlink('/tmp/mytmpfile')
   [do whatever you want with fp]

No matter what happens to the process, you KNOW you aren't going to leave
your temporary file around.
