killough 1/98:

|
This fixes some problems with exit handling
|
|
during abnormal situations.
|
|
|
|
The old code called I_Quit() to end program,
|
|
while now I_Quit() is installed as an exit
|
|
handler and exit() is called to exit, either
|
|
normally or abnormally. Seg faults are caught
|
|
and the error handler is used, to prevent
|
|
being left in graphics mode or having very
|
|
loud SFX noise because the sound card is
|
|
left in an unstable state.
