As mentioned previously, move->fdes looks in the port table to see if
the file descriptor things are being moved too is still in use, and if
so, moves that (fd, port) out of the way first, so should be safe.

That only works if Guile knows about the fd though, and Guile currently
does not know about it's own finalisation pipe, which I think is the
cause of <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=48563>, so
currently still fragile ...

(To be clear, I still recommend just fixing dash ...)
