Why do they surprise you?

We already only instrument the interesting edges ;-)  We only add
instrumentation on edges that are not on a spanning tree of the CFG.
Selecting the interesting ones from that subset of all edges sounds
a bit strange, because the whole point of profiling is to _find_
those interesting edges :-P
