Well, no one should be doing any parallel stuff in scipy by default.
I.e. a serial version of an algorithm should always be available. I
have no problem with people putting in parallel algorithms in addition
with whatever libraries they think are needed. We shouldn't impose any
extra dependencies, so we should treat these like we treat the
optional plotting helper functions that we have in

Pretty much all of the parallelizing libraries impose potential
incompatibilities; multiprocessing isn't exceptional in this regard.
