There was brief debate yesterday among the Pythonians in the lab as
to whether the MKL operates outside of the GIL, but it was general
understanding that it does.
It is still unclear to me whether Python/numpy compiled with MKL
would be freely re-distributable, as the MSVC version is.

I have been using shared memory and numpy with good results lately on
Win32 with tagged memory.
On *NIX, arrayfrombuffer(), mmap and MAP_SHARED, or POSH
seem like the ticket.
Whatever happened to pyGA?
GA http://www.emsl.pnl.gov/docs/global/ is still around.
