[ZODB-Dev] RelStorage PostgreSQLLocker deadlock/wait problem

Any insights from RelStorage users appreciated on this;
I have a case where multiple Zope2 instances (each with four threads)
get stuck (most/all threads) waiting on execution of LOCK TABLE
statements (presumably stuck commits) in
relstorage.adapters.locker.PostgreSQLLocker.hold_commit_lock [1].
Any ideas on what I should be looking for in PostgreSQL and possible
causes in my application?
