Well done pushing the investigation!

Are you sure these failures are Hurd-only?  When I see timeouts related
to dbus tests, I often think the problem may be attributed to #30948,
because dbus often waits for processes to die completely but are left as
zombies in the build container due to incorrect signal handling from the
Guile PID 1 there.  But since the glib package currently builds for
x86_64 at least, that's probably not it...

LGTM.
