The compare on removal is not needed afaics, and its also not used when
doing lookup to begin with, so we can just recompute it?

Isn't this a way too much overhead?

I don't think so.  This computation only occurs when we dump events
to userspace.

I personally favor Pablo's per-cpu counter approach.
That way the IDs are unique again and we get rid of the info leak without
much effort.

I have not seen these patches so can't really comment.
