I was wondering about the repetition; I've updated the ticket.

May I ask what is the point of using a SYNONYM-STREAM in the bug
examples?  Just using *STANDARD-OUTPUT* directly as the stream argument
still evidences the problem, so I don't understand the use of
MAKE-SYNOMYM-STREAM.  Is the potential problem that something in SLIME
or elsewhere might be rebinding *STANDARD-OUTPUT* between calls?
