Subroutine calls are indeed slow! -- This is what I got on the first test...

100,000 calls to a no-argument subroutine took 1:09.0 - the loop overhead
counts for 0:06.0 of that (see previous note), so we are talking of about
603 microseconds per call??? I'll look at the call instruction to see exactly
what it does, and what the return instruction (the only code generated for
a null body subroutine)....
