What I do is; 1) All thread objects get stored in a list, threads = [thread1, thread2, ...] 2) Each thread is running a loop in its run() method. Each time the thread executes an iteration of the loop, it checks a variable called threads_exit. If threads_exit == 1 then the thread breaks the loop and returns (effectively ending the thread). 3) To quit the application, first I use gtk.mainquit(), then I set threads_exit = 1. Usually some of the threads are idle because there is nothing to do... and those threads are blocked on a condition so I use notifyAll() on the condition to wake them up. Then I use for t in threads: t.join() which will block until all the threads have exited, and then the app will quit. The most common problem with this is that an exception will happen somewhere and a thread will die w/o releasing some locks. Then when I try to quit the application will hang (blocked on the join() of a stuck thread) and I use killall -9 to force it to quit. This can usually be avoided by using try: except: blocks to release locks after an exception is thrown. Using this I am actually able to keep the application running smoothly in spite of errors. Its a complicated solution, but it is necessary for my application. If you want to try it, be prepared to spend about a week getting all the threading problems worked out. :) --- Andrew W.
