[Cython] OpenMP support

[Hoyt Koepke]

Apologies for the OT post, but a quick FYI: I've been using openmp
with cython pretty extensively, usually wrapped in static inline or
template functions in a separate header.  However, I've been hindered
by a strange bug that seems to appear when python loads gomp, gcc's
openmp implementation (http://bugs.python.org/issue11275).  For me, it
causes matplatlib to become unusable. I don't know if it's a bug in
matplotlib, in python, in gcc, or what -- a better programmer than me
could probably track it down -- but it has definitely made working
with openmp/cython a pain.
