Note that you see many of the same problems with signal handlers (including only being able to call reentrant functions from them). Most advanced Unix programming books say you should treat signal handlers in a manner similar to what people are advocating for remote thread stoppage in this thread: unless you're doing something trivial, your signal handler should just set a global variable. Then your process can check that variable in the main loop and take more complex action if it's set. -- http://mail.python.org/mailman/listinfo/python-list
