Summary: sys.excepthook doesn't work in threads

Initial Comment:
simple script to reproduce:

import sys, threading

def log_exception(*args):
    print 'got exception %s' % (args,)
sys.excepthook = log_exception

def foo():
    a = 1 / 0
threading.Thread(target=foo).start()

Note that a normal traceback is printed instead of "got
exception."

I've just run into this, and it's very annoying.  The stupid part is that
threads started with the thread module don't have this problem, it's just a
problem with threading.Thread()s trying to be too clever.

I would vote for deleting all the code to do with exception printing in
threading.py and letting the C machinery take care of it.
