We're seeing a problem where occasionally a process appears to be granted a
lock but miss its semaphore signal. It eventually gets the 60s deadlock signal
and notices that it has been granted the lock and gets back to work.
I haven't gotten any further than this in the forensic analysis and it's a bit
tricky as it only happens in fairly long benchmark runs. It seems to happen
every few hours of running at 3000+ transactions per minute...
