Simple: HP does this...there must be a reason.

They appear to do it on selected models of PA-RISC systems.  Why?  Don't know.

I can only conjecture...and the conjecture is the obvious one: there must be
some circumstance where GATE fails.  Otherwise, *why* replace it with
a slightly slower mechanism?
