Thanks for the replies. I guessed the situation would be flush() and trust. The probability of a crash between flush() returning and data actually written resulting in a trashed disk must be very small. But if you can be certain without too much effort it's got to be a good idea, so I thought I'd ask anyway.
How does the banking industry handle this sort of thing? Could be big bucks if something goes wrong for them! Thanks again, John -- http://mail.python.org/mailman/listinfo/python-list
