    Yes, that is a different problem as such -- but I guess we can
    find other cases where some activity is stalling redisplay when
    redisplay-dont-pause is nil.

This is not exactly a bug in Emacs, it is a bad interaction.  I will
not claim it necessarily indicates a bug in some other program, but I
have a feeling that that is so.  Anyway, we don't know of a case where
it occurs except due to a bug in some other program.

So I think we need not worry about this now.  If and when we find
a case where this happens, and we don't think the other program
is at fault, we can think about what change is needed in Emacs.

    That is a work-around for one manifestation of the problem...

Is any other manifestation known?
