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. > I'm going to run Guile + Boehm GC + SND for a while now and report > back if anything unusual happens.

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!
