Notes:	this vector is overwritten when GO32 starts but is not restored by
	  early versions of the extender
	the newest versions of GO32 dynamically allocate the vectors used
	  for the relocated IRQs, much as DESQview does (see INT 50"DESQview")

	  "SPOOLER" with INT 21/AX=3D02h, place it in RAW mode with
	  INT 21/AX=4400h and INT 21/AX=4401h, then read one byte which will

Program: KILL.COM is a TSR utility that allows you to terminate programs

	 QKILL.COM is a modification of KILL.COM by Solar Designer that
	 supports QEMM's Quick Boot feature
Notes:	This interrupt is intercepted but not chained by KILL.COM; it is never
	  called by KILL.COM itself. It points into the middle of KILL.COM's
	  INT 09 handler and assumes specific values have been placed on the
	  stack (thus it can't be called as an interrupt).
	To invoke KILL, use the following code:
		pushf
		push cs
		push offset $+0Dh
		push ax
		push es
		push 0
		pop  es
		jmp  dword ptr es:[96h*4]
