bug#7276: 23.2; do-applescript can lock Emacs uninterruptedly

[Daniel Pittman]

Evaluating the following code caused Emacs to refuse to return to user
control; I was unable to interrupt the process in any way:

  (do-applescript "tell application \"unknown app\" to activate")

That popped up the "which application did you mean" dialog, which I cancelled
with ESC, and Emacs simply never returned from that call.

Regards,
        Daniel
