I somehow feel that we should be trying to get rid of cases where WaitLatch is not desired. That's probably overly simplistic - there might be cases where the caller isn't just polling and has a really legitimate need to wait for 5 seconds of wall clock time. But even in that case, it seems like we want to respond to barriers and interrupts during that time, in almost all cases. I wonder if we should have a wrapper around WaitLatch() that documents that if the latch is set before the time expires, it will reset the latch and try again to wait for the remaining time, after checking for interrupts etc. -- Robert Haas EDB: http://www.enterprisedb.com
