Wouldn't it be better to either skip the test on kernels with debuging
confing options on? Or multiply the timeout we got from the callibration
when we detect a debugging kernel?

The problem is that any number we put there will not be correct in a few
years as CPU and RAM speed increase and the test will be effectively
doing nothing because the default we put there will cover kernels that
are overly slow on a future hardware.
