benno measured N>=4000, not sure where its coming from
I know we cant get it in 100% of cases (say broken hardware) but in the
case of known *good* hardware configurations is N<=5 a reasonable target?
Right now even with known "good" hardware we are lucky to get N<=200
At the very least we should keep a list of known bad hardware with
the reasoning behind it (eg ps2 mouse?)
I suspect if people start looking there may be clean ways to deal with
"bad" hardware and still get good latency without convoluted kernel code.
