I wonder how hard this problem would be to hit in normal use. I mean, a few hundred or a thousand clients doesn't sound that crazy. This case depends on an open deny, but you could hit the same problem with file locks. Would it be that weird to have a client trying to get a write lock on a file read-locked by a bunch of other clients? --b.
