hmmm...  GenGC per se won't be helpful here, I'm afraid.

can you check where (code-wise) does Guile touch a lot of pages?  if
it's under scm_gc_sweep, than perhaps I should implement lazy sweeping 
first...

you could also try configuring a recent Guile version with
--enable-debug-malloc and see whether you leak smob memory.
