No it is not the same. Apache will still be non threaded and only prefork MPM can be used. > There be dragons, as noted above.

Does this mean I can use threads from Python? As above, Apache does not acquire threadedness. Preloading the library will be enough to satisfy unresolved symbols which Python wants. Yes you should be able to use threads in Python. I can't understand why this thread problem still persists on FreeBSD after all these years. Why can't they fix it? Graham
