My opinion on this continues to be -1.  I'm afraid that difficult access 
to OpenMP on Windows platforms (lack of OpenMP in MSVC Express is, as I 
see it, a major showstopper, although perhaps GCC 4.x on Win is stable 
enough already, I don't know) would prevent of *true* portability of 
OpenMP-powered Cython programs.

IMHO, going to the native Python threads + possibly new Cython syntax is 
a better venue.  But I'd like to be proved that the problem for Win is 
not that grave...
