Yea, we can likely just trash it and wait for people to complain about the
keyboard being hung. I doubt we'll get any complaints because Xaccel 2.1
was quite a long time ago... It is no longer relevant and the original
conditions
that caused the lost interrupts are likely long gone...

And if they aren't, we'll get a reproducible test case to judge what the
right workaround
should be.
