I have embedded python as a midi scripting language in my audio thread, and need to migrate the calls to libpython to a new process per each audio thread to avoid acquiring python's the global interpreter lock (GIL). Does anyone know what the theoretical reliability of basic memory-based IPC mechanisms are like with respect to realtime audio threads? Will I be causing even bigger performance problems with just the IPC overhead to make some function calls, or is it negligible? Thanks
