I thought factoring was something that was able to be made
faster with parallel processing?

I notice on linux and cygwin, only 1 cpu being used.

If someone **really** wanted to speed things up, I think using
video cards that support much larger parallelism, would likely
be a big boost... but that would be even more likely to be
a _little used feature_.
