That was the problem, you didn;t tried my code ... you just trusted your
theory.

Maybe there are more than one good theory?

I really don;t want to start this discussion here again, before v2009.03 is
released, but we did such an analysis, and I posted patches for example
how we can do the bitbang driver in another way. You just ignored it. If
you did a analysis of the code I posted, you would have seen that for the
bitbang driver our sourcecode changes were minimal, and resulting
codesize is smaller than in your approach. But please, starting with
this discussion when code is public ...
