Slightly off-topic, but could I get back to per provider and per
database lock tables whilst we are on the topic of lock tables?

I remember this was discussed at the end of a SAS session during the
2005 Prague conference. My recollection of that discussion was that
Jim and Ann both thought that per database lock tables were a good
idea that had been considered in the past.

Again in my recollection, Ann said that the reason for not doing per
database lock tables in the 80's was the limited supply of semaphores
on old Unices (16, or even 14, system-wide; these days 4096 is more
normal).

Looking forward to hearing opinions about the benefit and feasibility
of per database lock tables.
