Summary: decimal module borks thread
Initial Comment:
I got across this while trying to use MySQLdb in a
thread. Since MySQLdb imports decimal I got the same
error there.
Code: (This happens in both 2.4 and 2.5)
import thread, time, sys
if len(sys.argv) > 1:
import threading
def test ():
import decimal
print 'Exiting test.'
thread.start_new_thread(test, ())
time.sleep(1)
Output:
$ ./thread.py 1
Exiting test.
$ ./thread.py
Exiting test.
Error in atexit._run_exitfuncs:

I believe it is an issue with the import lock.
If you 'import decimal' prior to starting up your subthread,
everything will run fine.
