flock experience

[Robin Becker]

has anybody good experience using file locking in python. I have the
typical problem of opening a log file for a short time (cgi environment)
in a multiprocess world. So far I think we have been lucky, but our 8
machine front end is contracting to one machine, just for us, so the
collision probabilities are rising. I see there's a recipe in the pcb,
but what happens to locked out processes etc etc.
