This is totally subjective, but I seem to have a vague memory of running in to the undo limit sometime in the last few months. It doesn't happen very often, though, and in cases where I'm likely to use that much undo I'm just as likely to do a VCS revert. > (I personally don't feel strongly about this either way, but I can see > how it can be surprising to users.

The documentation for `undo-limit' doesn't say, and the relevant section in the Emacs manual doesn't clearly state it either. - Michael -- mouse, n: A device for pointing at the xterm in which you want to type.
