I just found out that I can not mmap /dev/fd0. Looking at the source,
it seems that mmap is only supported for a few character devices.
I think mmap should work for any seekable device. Why not?
Block devices could even be supported as a group.

(I would hope that pulling out the floppy sends SIGKILL)
