I am too, but this one is too visible to make generic.

Well it's a pretty big behavior change.  I found that when it is in place if I
close my lid and then open it immediately I can't wake up immediately because
that 2.5s hasn't passed yet to even start the suspend.

Or if I close my lid before putting a laptop in the bag I would expect all the
fans stop before I put it in the bag.  Well now you close your lid and the fans
are still running?  That makes you think there is a problem, so you open it
back up to check.

If we're going to keep "some" variation of it around for everyone I would
rather it be on an interruptible timer, which means maybe putting it somewhere
earlier in the sequence that interrupts are still enabled.

I don't really know what could be different with what Linux does with the EC in
these two cases, and hopefully that gives us some insight on the best solution.
