I was seeing this more than occasionally for a while. :-/

What I'd like is an easy way to abort a dump that's in progress, like
by hitting spacebar or something. Then there's no need to push the
reset button, and the ordering becomes less important.
Turning dumps off isn't a good solution in general because the value
of a dump depends heavily on what happened leading up to it.
