just found this in another newsgroup
A Python *program* can utilize more than one core, just Python *code*
can't run on multiple cores in parallel. Everytime a C function calls
code that doesn't use the Python API it can chose to release the GIL.
That way a Python program can wrap a library and use as many cores as

although not in PyQt but in wxPython: PyLab_Works, 100.000+, rockstable !
