Comment (by mboes):

 I see! That makes sense. So shall we close this ticket and open a new one
 for documentation? What we want to document here I'm guessing is simply
 that the behaviour of registerFd is system dependent, and that some
 systems might impose restrictions on the types of FD that work and ones
 that do not.
