nope, once you have your low level Ada compiler bootstrapped then
you can do the operating system task switching entirely in terms
of Ada task switching. Thinking you have to use ASM to do task
switching is exactly like thinking you have to use ASM to do a
hardware addition. Yes, there is a bootstrap problem, but given
Ada compilers on other machines, that is easily solvable.
