This won't be reasonable until its performance improves drastically,
especially if you're going to emulate multiple machines. Grab the code and
run it, and you'll see what I mean.

Due to its performance, this might not be the best advertisement in the world
for Linux. Also, the target OS needs something very similar to clone, plus a
pretty general mmap. As far as I'm aware, even most Unices don't qualify.
