Counting Threads

[David Poundall]

First time I have used thread locking.  This seems to work but is it
correct?

from threading import Thread, Event, Lock
.
.
.
    def launch(self, ThreadTitle, SubToLaunch, SubsArgs=(),
SubsKwargs={}, AsDaemon=True):
        my_lock = Lock()
        my_lock.acquire()
        try:
            # ---------------------
            t = Thread(target=SubToLaunch, args = SubsArgs, kwargs =
SubsKwargs)
            t.setDaemon(AsDaemon)
            t.start()
            self.Threads[len(self.Threads)] = t           # Stash the
thread in an instance local
            # ---------------------
            ServerThreads.threadcount += 1
        finally:
            my_lock.release()
.
.
