The open file database is self-cleaning (killing the smbd process
holding the entry - NOT VIA kill -9, but normal kill) will cause
the next opener to clean out the old entry. The file lock database
(byte range locks) currently is not (it used to be until we ran
into a resource issue with fcntl locks on Solaris). I've committed
a fix to make it self-cleaning again for 3.0.23.
