In the nine months since Ken's change, I've noticed a problem with
Emacs twice.

Ken, Eli, are you going to be running Emacs with that patch installed?

I can't get my head around the idea. If we don't care whether or not
the action in question has finished when SendMessage returns,
then why are we using SendMessage? And if we do care, then
shouldn't I expect weird bugs caused by timing out when the system's
under load?
