I'm sure Tim was aware of the removeHandler function. But this is
still reaching into log.handlers - although IMO it's safer to reach in
and read than to reach in and mutate. So without the implications of
Tim's inability to read docs, this is a viable suggestion. I'd prefer
this over the original "del log.handlers[:]".
