Actually, I am tempted to do it for the slower code currently in the
main tree, but then I am worried that it'd make integration of faster
SIMD-enabled code trickier.  Yet I might do it.  It'd be very nice to
say that a certain JtR release supports parallelization of _all_ crypt(3)
hashes that it supports at all, as well as of those that it only
supports through c3_fmt.c (so it will be all in that sense, in fact).
That would be good for marketing, even if -jumbo's intrinsics code
performs better. ;-)

If I do it, can I count on you for rebasing -jumbo on that updated main
tree (not necessarily introducing similar parallelization for its code,
but merely making it work like it does now)?

Thanks,

Alexander
