and the precise symptoms of the bug:

When i want to run snake-big-play from silly.el (posted recently on
gnu.emacs.sources) Emacs crashes with a fatal exception. First i
thought it was some problem with sit-for, but I can reproduce it
without as well.

To reproduce:

- start emacs with "emacs -q"
- open a file containing the following text (using C-x C-f bug.el)

(setq snake-height 44
      snake-width 98
      snake-buffer-height 46
      snake-buffer-width 100)
(snake)

- run M-x eval-buffer RET.
- voilà, Emacs crashed.

Thank you for the report. It does not seem to be a bug in any
particular lisp function, as if I run snake using the lisp debugger,
Emacs does not crash. The stack trace suggests a timing problem in
redisplay.

This problem doesn't appear under current CVS, so I think this is
probably related to another bug that has been fixed already.
