This file is used by other users and by other windows in
my program.

I cannot use FLOCK(): other users from network
may have placed locks into this table so flock() fails.

I use this table as grid recordsource and as a target of a
SET RELATION command. Closing it using USE leads to sophisticated code
to re-use it.
