Would someone like to guess in some times for these operations?

	Driver				Daemon
	------------------------------------------------
	backend traps to request lock	backend traps to write lock request
	kernel grants lock		backend resumes
	backend resumes			daemon resumes
					backend traps to wait for reply
					daemon grants lock
					daemon traps to write response
					backend resumes
					daemon resumes
					daemon traps to wait for request

A daemon may be available as an alternative to the driver with some
versions of INGRES 4.0.  I am collecting this net discussion, but you
might also profitably call tech support to voice your interest.

This is only my opinion.  Nobody here would mistake it for the company's.
