Desk accessories get AC_CLOSED messages when an application calls
appl_exit.  That's the only time the AES sends AC_CLOSED messages.
Of course, if an application has already terminated, it can hardly
be calling appl_exit ;-).

The desktop itself also calls appl_exit on a resolution change and
just before* an application is launched (to tell the AES that it is
exiting).  The AC_CLOSED messages that the desktop sends to accessories
don't mean that they're going to lose anything, because the desktop
never really terminates as such (except on a resolution change).

Yup.  If you don't care about double click reporting, always lop off
the high bit of the return from form_do before using it as an object
index!
