Hmm.  I'd be interested in hearing a little about these issues.  It
might be tolerable to destroy performance if that's the only way to
solve the problem in a reasonable amount of time--we're not
constrained by Scheme performance at all, so a further decrease might
be only semi-noticable.

Is there documention for this, or should I read the source?

I'll have a look.  Thanks!
