Done:

Looks like the user wasn't force unmounting the FS.  There really
isn't any problem w/ kqueue, as a normal unmount is expected to be
refused while files are open.

I guess there COULD be a new flag added to file descriptors that
flag them as being able to be closed upon unmount.  Then when an
unmount happens and only these flagged files remain, they are closed
allowing the fs to unmount.  But this is a new feature and independent
of kqueue.
