For instance, when you terminate the programm using 'HX'. On our computer
the interrupt-handling routine is in this case still active (but we have
an early release of VM/SP, may be not 100% compatible with the IBM-Original).

It depends on what you will do in this 4 minutes or where the interrupt-
handling routine was loaded. If it was nearby address x'20000', than better
do nothing (no xedit, no call of user-programs). If it is a nucleus extention,
it should work (if the extention was not dropped).
