INT E0 - DR Multiuser DOS - "P_DELAY" - DELAY EXECUTION

	CL = BDh
	DX = delay in system ticks (typically 16.6 ms/tick)
Return: after the delay elapses
	no results
Notes:	the length of a system tick is installation-dependent (typically
	  1/50 or 1/60 second); the length may be determined by reading the
	  TICKSPERSEC value from the system data segment
	the actual delay before the process is rescheduled to run may be up to
	  one tick longer than requested; the delay between rescheduling and
	  actual execution cannot be predicted if higher-priority processes
	  are awaiting a turn at the CPU
