Log Message:
-----------
Add code to catch deadlocking against self (e.g. opening 6 cursors when you
belong to a queue with active threshold 5).
This could be used to handle the case of 1 statement with a cost higher than
the queue cost threshold (currently allow overcommit if it is the only active
statement).
