Title: DOC: site.cfg: warn against OpenBLAS and multiprocessing

Fixes #654 by not fixing it; I don't think NumPy *can* actually fix the problem as it's a design flaw in Python's multiprocessing. Listed various alternatives (Python 3.4 forkserver, single-threaded OpenBLAS, Python threading).

Maybe @ogrisel wants to chip in on this one as well?
