its worth noting that this is precisely what Be say about the
BeOS. there is at least one driver (for a gaming joystick) that is
known to destroy the low latency figures for the kernel.
thats OK by me, if its documented and made public ("if you are doing
low latency stuff, do NOT use the foobar-XYZ module because ...").
