Re: compose and blink-cursor-mode

[Richard Stallman <rms@gnu.org>]

    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.

Can you run emacs under gdb and suspend it while it is waiting, and
make a backtrace?  Maybe you can find out what it is waiting for, and
why.
