INT 2F U - Novell DOS 7 TaskMGR - ???
AX = 271Ch
DX = ???
bit 0: ???
Return: ???
---if DX bit 0 set---
AX = 0031h
CX = 0000h
BUG: if the task switcher is running, and DX bit 0 is set on call, this
function will crash because its exit code attempts to pop several
registers which are not pushed when DX bit 0 is set
