Well, I am willing to do more string copies if really
necessary.  I used to do a demangle for function names that
malloc et al was called from every call to malloc.  But
in the mean time I wrote a cache for that so that each function
that calls malloc/new will only be demangled once.

But... I like the iterator idea a lot more and will hopefully
do that :)
