Thanks, I didn't know that multiprocessing Managers could be used with processes not started by multiprocessing itself... I will give them a try. I just need to compute FFTs, but speed is a real issue for me (I am using the results for real-time feedback). To be honest I don't know yet if the FFT

Hi all, While I realize that this is certainly tweaking multiprocessing beyond its specifications, I would like to use it on Windows to start a 32-bit Python process from a 64-bit Python process (use case: I need to interface with a 64-bit DLL and use an extension (pyFFTW) for which I can only fin
