+ − 3022
+ − 3023 Expected exits occur when the user directs XEmacs to exit, for example
+ − 3024 by pressing the close button on the only frame in XEmacs, or by typing
+ − 3025 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
+ − 3026 buffers, and then exits using the primitive `kill-emacs'.
+ − 3027
+ − 3028 However, unexpected exits occur in a few different ways:
+ − 3029
+ − 3030 -- a memory access violation or other hardware-generated exception
+ − 3031 occurs. This is the worst possible problem to deal with, because
+ − 3032 the fault can occur while XEmacs is in any state whatsoever, even
+ − 3033 quite unstable ones. As a result, we need to be *extremely* careful
+ − 3034 what we do.
+ − 3035 -- we are using one X display (or if we've used more, we've closed the
+ − 3036 others already), and some hardware or other problem happens and
+ − 3037 suddenly we've lost our connection to the display. In this situation,
+ − 3038 things are not so dire as in the last one; our code itself isn't
+ − 3039 trashed, so we can continue execution as normal, after having set
+ − 3040 things up so that we can exit at the appropriate time. Our exit
+ − 3041 still needs to be of the emergency nature; we have no displays, so
+ − 3042 any attempts to use them will fail. We simply want to auto-save
+ − 3043 (the single most important thing to do during shut-down), do minimal
+ − 3044 cleanup of stuff that has an independent existence outside of XEmacs,
+ − 3045 and exit.
+ − 3046
+ − 3047 Currently, both unexpected exit scenarios described above set
+ − 3048 preparing_for_armageddon to indicate that nonessential and possibly
+ − 3049 dangerous things should not be done, specifically:
+ − 3050
+ − 3051 -- no garbage collection.

+ − 3053 -- no messages of any sort from autosaving.

+ − 3056
+ − 3057 (Also, all places that set preparing_for_armageddon also
+ − 3058 set dont_check_for_quit. This happens separately because it's
+ − 3059 also necessary to set other variables to make absolutely sure
+ − 3060 no quitting happens.)
+ − 3061
+ − 3062 In the first scenario above (the access violation), we also set
+ − 3063 fatal_error_in_progress. This causes more things to not happen:
+ − 3064
