hmm., that certainly is part of the answer :) but, why makecontext()
doesn't/cannot fill up some appropriate(??) values automatically into
such fields? -- it looks to me the machine context makecontext() have
to fabricate is simply the one to start calling the given function as
one of its argument (= its second arg: "void *func()"). and it appears
to me that this new machine context doesn't have anything to do with
that of the caller. this make me think getcontext() may not be
necessary. -- ?? (well, obviously I'm missing something)
