You're missing something obvious.
FORCE-OUTPUT and FINISH-OUTPUT each take optional arguments which
specify what output stream they affect; this argument defaults to the
stream which is the value of *STANDARD-OUTPUT*, and this likely isn't
what you want. In your example, calling either
will cause any data in the stream's buffers to be sent to the OS.
(There was a discussion of the differences between these functions on
this list a week or two ago; I don't want to repeat that, but I think
that in most cases FORCE-OUTPUT suffices.)
Streams in CCL are almost always fully buffered.
