True - then again, we could make func1 of zero cost - pushing all its
self cycles up into its caller (?) so it still exists in the call tree,
but with an apparently instant effect ? ;-)

So - I guess the problem is then when functions call themselves,
perhaps some recursive 'qsort' caller when glibc is hidden ( or whatever
similar madness ;-).

Not sure :-) I guess we prolly want to build (or re-use) some simple
test code - does kcachegrind have a couple of test libraries that it can
be used to profile ?
