this basically allows the threads to exist in these logical CPUs, undisturbed, and without trashing each other's cache
this could improve performance, very tricky thing to pull off correctly, but again, this is mostly an experiment
will mainly benefit: Linux, Android, FreeBSD, Windows (not ARM)
Additionally, this means no context trashing :)
