> I've been meaning to write a slow hook detector for a few weeks now. Feel free to beat me to it. I figure we can start by just calling each entry in the major hooks with a new run hooks (with args) variant that records times of each and reports anything over a threshold as a warning.

I think that would be a very useful feature.  But it won't find this
particular problem, because project.el doesn't use a hook to update
the mode line in this case.
