102 GNU Emacs version 15 (15.34) was released on May 7, 1985 and

427 /* Ben's capsule summary about expected and unexpected exits from SXEmacs.
429 Expected exits occur when the user directs SXEmacs to exit, for example
430 by pressing the close button on the only frame in SXEmacs, or by typing
431 C-x C-c. This runs `save-buffers-kill-emacs', which saves any necessary
432 buffers, and then exits using the primitive `kill-emacs'.
434 However, unexpected exits occur in a few different ways:
436 -- a memory access violation or other hardware-generated exception
437 occurs. This is the worst possible problem to deal with, because
438 the fault can occur while SXEmacs is in any state whatsoever, even
439 quite unstable ones. As a result, we need to be *extremely* careful
441 -- we are using one X display (or if we've used more, we've closed the
442 others already), and some hardware or other problem happens and
443 suddenly we've lost our connection to the display. In this situation,
444 things are not so dire as in the last one; our code itself isn't
445 trashed, so we can continue execution as normal, after having set
446 things up so that we can exit at the appropriate time. Our exit
447 still needs to be of the emergency nature; we have no displays, so
448 any attempts to use them will fail. We simply want to auto-save
449 (the single most important thing to do during shut-down), do minimal
450 cleanup of stuff that has an independent existence outside of SXEmacs,
453 Currently, both unexpected exit scenarios described above set
454 preparing_for_armageddon to indicate that nonessential and possibly
455 dangerous things should not be done, specifically:
457 -- no garbage collection.
459 -- no messages of any sort from autosaving.
460 -- autosaving tries harder, ignoring certain failures.
461 -- existing frames are not deleted.
463 (Also, all places that set preparing_for_armageddon also
464 set dont_check_for_quit. This happens separately because it's
465 also necessary to set other variables to make absolutely sure
466 no quitting happens.)
468 In the first scenario above (the access violation), we also set
469 fatal_error_in_progress. This causes more things to not happen:
471 -- assertion failures do not abort.
472 -- printing code does not do code conversion or gettext when
473 printing to stdout/stderr.

2595 execute both of the main_1 calls and the second one must
2596 not touch the first computation because argc/argv are hosed
2597 the second time through.
2599 sxemacs -- Only the second main_1 is executed. The
2600 invocation path must computed but this only matters when
2601 running in place or when running as a login shell.
2603 As a bonus for straightening this out, SXEmacs can now be
