Subject: bug#10738: insert before setting the mark means the mark wont be set
Date: Mon, 6 Feb 2012 12:57:36 -0500

From emacs -q, consider the following program:

(defun foo ()
  (interactive)
  (insert "bar")
  (push-mark)
  (forward-line)
  (activate-mark))

M-x foo, bar appears, but the mark is not set.

(defun baz ()
   (interactive)
   (push-mark)
   (forward-line)
   (activate-mark))

I wouldn't expect a command *before* setting the mark to affect if the
mark was actually set. Is this a concurrency bug?
