Do you assume there is but 1 single session blocking the waiter? False in cases where some N number of sessions are all holding less invasive locks and you are pending on a heavier one. To wit; share locks granted and an exclusive locker pending. The question in regards to whether it's possible to log more info here in any case isn't something I can answer personally.
