My apologies about this, by the way: I had prepared that patch stack
last summer and was witholding it until the IRQ-fires-only-once
situation was resolved (it does affect at least the onkey subfunction,
although in a non-obvious way when the event triggers a shutdown or a
reboot). I did not think of checking recent submissions until it was
too late.
