Hi,

Right, "interactivity" may be an important metric for some classes of
applications, albeit one that can sometimes be hard to capture.  That
said, I guess a "large fraction" of Guile users will be even more
concerned about memory consumption and execution time.

Alright, I'll wait for bug reports.  ;-)

Cool, let us know how it goes.

I'll probably sync my `boehm-gc' branch with HEAD one of these days, too
(I think it doesn't lack a lot of upstream changes anyway).

Thanks!

Ludovic.
