Wait, so you're writing that it takes between 3 and 4 times longer to
load the shared libraries than just the plain scheme code?  Scwm is
plenty fast executing Scheme code (and when it's not fast enough, we can
just write a new primitive)--- it's plenty slow *loading* and that's what
I'm hoping to speed up.

Please let me know that I'm misinterpreting your performance numbers.

Thanks,
