Any other suggestions?
The problem is that thread-killing (in the literal sense) doesn't work. Unlike processes, there's no thread-environment encapsulation at the OS level, which means that things don't get cleaned up properly. Even Java has mostly given up on thread-killing. The only way to kill threads safely is to have them terminate themselves. Your other option is to use multiple processes. -- Aahz (a...@pythoncraft.com) <*> http://www.pythoncraft.com/ "If you think it's expensive to hire a professional to do the job, wait until you hire an amateur." --Red Adair -- http://mail.python.org/mailman/listinfo/python-list
