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. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
