Thanks for the report.  It's a bit irritating as I imported the gnulib
accept4 wrapper for precisely this reason!  I guess the gnulib accept4
wrapper doesn't actually provide SOCK_NONBLOCK or SOCK_CLOEXEC support.
Irritating.  I guess we should provide dummy definitions and a fcntl
fallback, and probably on the Guile side for now I guess.
