Well... Looking at the patch again, I thought "but it can't be right
to do a display to port, when port comes from open-input-pipe". And
then I tried running the test again, with the patch in place, and:
ERROR: open-input-pipe: no duplicate - arguments: ((wrong-type-arg
"display" "Wrong type argument in position ~A: ~S" (2 #<input: #{read\
pipe}# 13>) (#<input:
#{read\ pipe}# 13>)))
I'm not currently sure why I missed that before, but I'm working on a
better patch.
