Here's a new version of the patch which fixes various shortcomings
I noticed while trying it out.  Also it shortens the wait times after
displaying a message by applying the `sit-for` principle of not waiting
if there's some "pending input" (where I consider `emacsclient`
processes to be pending inputs as well).  This way, the `sit-for`
waiting times don't accumulate so much.

Also I noticed a weird thing in

Why do we wait for 5s in one spot but 1s in another?
