Yes, I'm not trying to argue it's perfect.  Just that I'm satisfied for
my own use.  Of course we should try to minimize the number of cases
where it hides useful info.  One possibility is to try and provide
better control so the user can prevent eldoc from showing up while she's
reading a previous message, and so that she can remove the eldoc message
to recover the previous message.

What kind of problems did you encounter (other than the one below)?

That could make sense, yes, since that's what would happen if the
deletion had taken place while the frame was displayed.  But we could
also fallback to the current behavior in that corner case, since
I'd assume it to be rare anyway (i.e. not worth spending too much time,
at least for now).
