Are 2 and 3 new with this patch, or were they present in the previous
code as well?
And what do you expect to happen when you press M-x while Emacs is
still busy performing your previous command? Having the visual
response delayed until the previous command finishes is normal Emacs
behavior, being a single-threaded program which executes commands one
by one in the same thread.
