[New-bugs-announce] [issue11166] No exit when daemon thread is running.

New submission from Dan Mahn <dan.mahn at digidescorp.com>:

I have a python-based test script that creates a daemon thread.  The foreground basically runs a loop of commands, while the daemon thread sends some UDP data on the network.  To stop the script, I use Control-C.  This is running under 64-bit Windows (Vista) with 64-bit Python.

This script was developed under Python version 3.0, and has been running fine with 3.1.  I downloaded 3.2RC1 and noticed that the script does not exit with the typical Ctrl-C.  I also tried 3.2RC2, which had the same effect.  If I do not start the background thread, the test exits normally.

If I use Python 3.1, but I don't set the daemon attribute on the background thread, the operation duplicates the problem.  Therefore, I believe there is a problem with 3.2 handling of daemon threads.
