On linux it's pretty easy to do, just setup alarm signal. On windows it's not so trivial to the point you cannot do it using python.org distribution, you will need to poke in low level C API using win32 extensions or ctypes. AFAIK twisted package <http://twistedmatrix.com> has some code to help you. Also take a look at buildbot sources <http://buildbot.sf.net> that uses twisted. Buildbot has the same problem as you have, it needs to kill run away or non-responding processes. -- http://mail.python.org/mailman/listinfo/python-list
