Yeah I got it all wrong. I'm trying to find the real bug
(likely in the trigger consuming driver) and fix that instead.

What do you use when stress testing IIO stuff? I have
been using the tools from the kernel so mainly
lsiio, iio_generic_buffer and iio_event_monitor so far.

iio-sensor-proxy seems really nice, but I just haven't
figured out what kind of programs people are in turn
using that with..
