This is not good enough, IMHO. Alexey Dejneka sent in a patch for gnumach
that does the same, and it works just fine. But after doing:

settrans -ag /cdrom

you have to do

settrans -ag /dev/hd3

(or whatever your CD ROM device is) as well, or the CD ROM remains busy.
I consider this to be a bit inconvenient, and also repetitive. In fact, we
don't handle removeable media well currently (CD ROM, ZIP).
I think that storeio should release such ressources it doesn't need anymore.

Thanks,
Marcus

Fixed since some time.  The revocation call at kernel level is missing,
though.
