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 ...)
