I'm really not sure why you want to move the files around. Here are two
different approaches from the one I initially gave you that deals
perfectly well with a directory where files are constantly being added.
This is a third approach - simpler than Bruce's.
Each process chooses any file and tries to rename/move it onto a different
directory. Rename is an atomic operation (at least on POSIX) so no locks
are required. If the rename fails, choose another file and try again.
