I'm going to work on a revised set of patches that makes things less
ugly. I'll also attempt to split out the arch-specific code bits so
that adding arm support, for instance, should be easier. The current
behavior of the patches does not please me because it changes the
behavior of the boot sequence without the user knowing. A more
explicit opt-in for creating threads will be employed.
