mod_python implements use Py_NewInterpreter() to create sub-
interpreters. They all share the same GIL. The GIL is declared static
in ceval.c, and shared for the whole process. But ok, if
PyEval_AquireLock() would take a pointer to a 'sub-GIL', sub-
interpreters could run concurrent on SMPs. But it would require a
separate thread scheduler in each subprocess.
