Actually, no, you don't.

Hint: There's probably a faster way to do it than checking *all* open files.

You can probably do even better if you explain *why* you want to find
all processes.  If you find them, what do you intend to do?  (Again, depending
on what you're trying to do, there's probably an easier way).
