This is actually the cause of the problem. (though calling it a
problem is not really correct)
At least with RTAI all of the realtime code already runs as kernel modules.

The realtime code needs to have a non-empty queue to continue to
execute in realtime, it can't afford to wait for input from
user-space.

But, sometimes the realtime code needs to wait for input from
userspace. At which point there needs to be a handshake.
