As a proposed fix, instead of acquiring the CheckpointStartLock in

any commit in progress transactions, after computing the new redo record
ptr, and wait for all of them to finish before flushing clog.
What sort of "wait for finish" mechanism do you have in mind? While
I've always thought CheckpointStartLock is a pretty ugly solution,
I'm not sure the above is better.
I was thinking of XactLockTableWait.
