Hi Nigel, Just one question: the documentation of get_lock() says that the lock is freed when a process terminates. Does this also occur with mod_php and persistent connections if a PHP script dies (say, due to fatal error or CPU limit timeout)? It isn't clear how mod_php works and why with persistent connections the "LOCK TABLES" locks wouldn't be freed but the get_lock() lock would. You were suggesting that I replace the LOCK/UNLOCK TABLES critical section with one implemented using get_lock()??? Or maybe you are suggesting something else ...
