My application is a TCP server having multiple client connectons. C++ PTHREADS are for each connected socket and the message received on the socket is evaluated by python functions. If I use only one process level python interpreter, then every thread has to lock the GIL & so blocking the other threads from executing the python code even if it is not the same python function that locking thread is calling.
-- That's why I tried using python interpreters per thread. But that also required GIL locking & so cannot be used. -- I cannot use python threads inside the Pyton intrepreter because then I will have to have some mechanism for communiaction between C++ Pthreads with these python threads. I think there is no way that we can achieve this because of the GIL being a process level state. Least I can do is have one python interpreter initialized in main thread and lock the GIL in every thread for python calls. -- http://mail.python.org/mailman/listinfo/python-list
