Are you using "zombie state" in the official meaning here (a process
that has terminated without its parent waiting for it, listed in a "ps
a" listing as Z)?  Or just as a colloquial description?

At some point of time, the terminal output was not routed through
whatever Guile considered to be its current-error-output but rather
through file descriptor 2.  If you have a blocking pipe or similar on
that in your process environment, this might be good for problems.
