The execution of signal handlers in python is not done really asynchronous - instead, an incoming signal is noticed and flagged to the interpreters byte code loop - so the signal gets dealed with when the current bytecode instruction is termintated. Read section 7.1 in the docs about the signal module. In other words: Don't worry, be happy. -- Regards, Diez B. Roggisch -- http://mail.python.org/mailman/listinfo/python-list
