The easiest way is just to bail out and don't try to be smart, that's
what I do now.

Another approach would be to just convert all my consistency
checks to warnings and skip invalid events (and hope it somehow works). I
think it makes sense when for some reason we have perf.data which
is not really consistent but we still want to get something out of it.

So you mean it perf record's fault?
