Unmasks all signals registered with this fd, meaning that the default
signal (interrupt) handler will deal with them from now.
Warning: this will simply unmask all specified signals. This could be
problematic if some completely different module has separately requested
that these signals be masked. If this situation ever arises we'll need
to come up with a clever solution involving some kind of reference
counting or something.
