I realise that Python already releases the GIL. I mentioned it as the reason why it possibly gets released and the other threads are getting in, not that we have to do it. :-) Anyway, import_module() is actually irrelevant in this case, as it isn't going to get called when the interpreter is being first created, but later. All the same, there will still be other stuff which can result in the GIL being released. This might be file i/o or it might be that Python will release it every so often when executing Python code in case there are other threads also running in Python code that want to do something. -- Graham Dumpleton (grahamd at dscpl.com.au)
