and the precise symptoms of the bug:

Hi.

This is a bug that I met only on freebsd boxes (freebsd 5 actually, I did
not test it on freebsd 4), with emacs 21.2 as well as 21.3 running in
XWindow mode. The XFree86 installed is version 4.3.0.

When blink-cursor-mode is disabled (and only in that case), and I try to
input a character using the compose key, a seemingly random time (roughly
between one and thirty seconds) elapses between the time I release the last
key of the compose sequence and the time the letter shows up on the screen.
If I hit another key (even a non-printable one, like shift), the letter
appears immediately.
