Well first there's a loud voice in my head telling me to eat Christian
babies and right after that my python program says 
"OSError: [Errno 24] Too many open files" 
or sometimes 
"IOError: [Errno 24] Too many open files: '/proc/mounts'" and exits.

Thanks. This tells me that some of my processes have a LOT of files
open, most of them pointing to /dev/hdc. Is this normal?
