Flags: callout or callback (usually hooked rather than called)

INT 2F - MS Windows - "VMPoll" VIRTUAL DEVICE - IDLE CALLOUT

	AX = 1607h
	BX = 0018h (VMPoll VxD ID) (see #02642)
	CX = 0000h
Return: AX = status
	    0000h if timeslice used
	    nonzero if timeslice not needed
Note:	when VMPoll makes this callout, all virtual machines are idle, and any
	  interested TSR can use the opportunity to perform background
	  processing
