Well, first it should be called once per second, not 60 times per
second, so something is wrong there...

Then, it wouldn't surprise me if the Pegasos RTAS didn't implement
the event scan properly. Maybe we failed silently before that ? I
doubt it's necessary there anyways.

It would be relatively easy to avoid starting the event scan on a
pegasos, I think we have a _chrp_type variable that can be tested
for that.
