   It might be really nice if there was a way to access stdin,
   stdout, and stderr as separate ports.  I might be willing to
   write some code for it, if someone could point me in the
   right direction.  But I really don't know where to look.

IIRC, ttn-do (http://www.gnuvola.org/software/ttn-do/) has a
child process module ‘(ttn-do zzz subprocess)’ that supports
such access.  It is not as automagic as ‘(ice-9 popen)’, but
maybe that's the right level for you.  If you look at the code
of both modules (highly encouraged :-D), you will see a fairly
similar pattern.  I think the best way forward is if Someone
migrates the (common) pattern into Guile proper, and exposes it
under a suitably coherent design.

Too many buzzwords, i know.  But i hope you understand anyway.

   Is there a way to do this that I don't know?

Only you know what you do not know, so who else can answer that?
Next question!  :-D
