Thank you very much.  I didn't anticipate such a difficult complicated 
cause.  The user agreed to try the patch tonight.  I'll report back the 
result as soon as I got it from him.

BTW, in LWLockWaitForVar(), the first line of the following code fragment is 
not necessary, because lwWaitLink is set to head immediately.  I think it 
would be good to eliminate as much unnecessary code as possible from the 
spinlock section.
 proc->lwWaitLink = NULL;
 /* waiters are added to the front of the queue */ proc->lwWaitLink = lock->head;
