This uses the
billiardlibrary instead of multiprocessing. It tries to leverage the spawning features so as to work better with BLAS libraries like Accelerate or OpenBLAS w/OpenMP enabled that are not fork-safe. By using spawning instead, this should create new clean processes that don't share memory bits that are related to these libraries and thus don't interfere with each other avoiding segmentation faults and other nasty crashes.
