(4 months later...)
I reproduced this EBADF thing with a 2.6.35 kernel on x86_64, and the
culprit turned out to be vfork: commenting out uses of vfork in the
daemon solved the problem.
That sort of ringed a bell, and indeed, Nix commit f794465c (Nov. 2012!)
disabled vfork for similar reasons.
So guix-daemon no longer uses vfork.
