(UNSIGNED-BYTE 8) will write to the stream one byte at a time,
rather than writing the sequence in one go, leading to severe
performance degradation.
+ As of sbcl-0.9.0.36, this is solved for fd-streams, so is less of a
+ problem in practice. (Fully fixing this would require adding a
+ ansi-stream-n-bout slot and associated methods to write a byte
+ sequence to ansi-stream, similar to the existing ansi-stream-sout
+ slot/functions.)
