er.  perhaps I was confused.

if I remember correctly, Guile has some logic to cope with suddenly
running out of file descriptors: it calls GC in the hope that some
port objects are unreachable.

I guess now you don't have to nesessarily do a full GC right away,
instead you may want to finish the sweep first and see if that helps,
and only do a new GC if finishing the sweep haven't helped.  hmm.  so
that's not as fiddly as I thought, and probably works as it is.

ditto for malloced memory, I guess.
