Int 7F Fn E1  - Alloy Mw386 - Get DOS Task Pid From Create Id              [N]

   AH = E1h
   AL = create ID (from AH=E0h)

Return: AL = DOS process number
   CL = memory size (00h=128K, 01h=256K, 02h=384K, 03h=512K, 04h=640K)

Note:  this function should not be called immediately after creating a new
     DOS task, since the new task is being initialized by a concurrent
     process
