some random sucesses ..
Ive been running an ipipe kernel as the default since shortly after 1/7.
Since then, Ive had a couple of freezes on boot,
and sometimes bash's auto-complete takes longer to complete,
but other than that, things have been solid.
But that kernel wasnt configured using scripts/prepare-kernel.sh,
so was missing the xeno_* modules.

This was run on a pentium-M laptop,
with cpu-clock running at 600 MHz, (capable of 1.7 GHz)
I presume this might explain the negative latancies.
Im aware this is un-supported ..
The only thing that looks wrong is the test-duration.
I asked for 120 sec, it gave me 40 samples.
The test did take 120 to run.
heres config, info, and -t1 and -t2 runs:
