r11435: Allow the hash size of the tdb open (locking) database

to be set in local.h. Change from the default (131) to
another prime (1049). Should this be an smb.conf tunable parameter
based on the number of open file descriptors available ?
If so what scaling factor ? More tests to follow.
Jeremy.
