Just for the avoidance of FUD, the GIL only affects threads, not
processes. Using the multiprocessing package leads to perfectly parallel
Python codes.  In Python 3.2 a fork/join framework was introduced which
works very nicely as well. So Python multi-threaded code is sequential
certainly, but then shared memory multi-threading is anathema!
