declaimed the following in gmane.comp.python.general:


>  >>Unhandled exception in thread started by
> Traceback (most recent call last):
> 
> Traceback (most recent call last):
>

	I'm not even going to attempt to figure out the traces -- the mere
presence of THREE "Traceback (most..." lines in a row seems to be a
clear indication that at least three failed threads are interleaving
their output.

	At this point, I'd probably try to install a thread specific
exception handler (even a wild card that catches all exceptions), which
uses a logger instance to IDENTIFY which thread is involved, and adds
that identification to the exception traceback data (or each thread logs
to a separate file named by the thread ID).
