AFAICS we never identified the cause. It was pretty clear that
something was failing to clean up shared-memory lock data structures,
but not what that something was. The last productive suggestion was
to add process-exit-time logging of whether unreleased locks remain,
but if Dave ever did that, he didn't report back what he found.
Maybe you could add such logging on your machines.
