You're not; it's in the FAQ, and there's a page devoted to it:
http://www.scipy.org/ParallelProgramming

I am surprised by the *particular* problem you have, that is, that the
GIL is not released *at all* for long periods by scipy; I think most
large pieces of compiled code in numpy/scipy operate outside the GIL
(and interpreted code releases the GIL frequently). This makes it not
just a parallel processing issue.
