Here is what I suspect he did in T::S::C. He might
have hinted at this when he was comparing the
performance of different platforms for the
decrementing loop. 

The code inside the block for the space-time
commands is compiled to the Parrot VM's byte-code
and sleep is compiled to no-op. All of this is
done just before execution-time using some
relative of Filter::Simple.pm

If the demo had been on a Pentium I might have
suspected that he was using the Pentium division
bug to somehow create a time-like loop on the
chip.
