I trace Emacs using Process Explorer, on a machine with 4 available cores I see 
25% utilization which (to my understanding) means it's at 100% on that core. It 
takes as long as 30 seconds to a minute to catch up.

If I do a non-trivial grep, my attempts to select files out of the grep results 
creates enough lag to make the selection process not usable.

Even when I do all the things to turn off tooltips it doesn't stop the 
behavior. I've tried these:

(setq tooltip-mode nil)
(setq show-help-function nil)

If there were a way to intercept the call to mouse-fixup-help-message so that 
it just does a "no-op" that would solve this for me.
