Read the code. I remember a delay on unmount at one time of local media the *was* the result of crap being in cache with 0 references to it but acting as a reference to the object. Now that I think more about it, it seems that those were executables and not normal files, since running acted as a reference, and for some reason you had to wait for it to time out or get pushed out of the lru list by new crap or something like that. So unless something is actually being run over NFS (I don't think that's the case) then an open dir ref is probably the problem. That going to be fixed in the next Beta disk?
