Re: inotify to minimize stat() calls

I looked into this a long while ago and remembered that rebase was
doing something like a git status for every commit that it made to
check the dirtyness.

This could be vastly improved by having an unsafe option to git-rebase
where it just assumes that the starting state + whatever it wrote out
is the current state, i.e. it would break if someone stuck up on your
checkout during an interactive rebase and changed a file,...

You could make it a lot safer than "just assumes", and the result
may become generally usable, I think.  For example, you can set a
"magic" bit somewhere in $GIT_DIR/rebase-i while you are in "I am
doing pick/pick/pick and the user will not interfere me" mode, and
clear that bit upon "rebase --continue".  And you cheat only while
that "magic" bit is set.
