I don't think we need the security stuff to see the impact of
backtrace.  We also use this code to find the caller's class and hence
the class loader to use for things like Class.forName().

I'd imagine a program like eclipse that uses class loaders heavily
would be sensitive to the performance of backtrace.  But I haven't
really checked, that is just supposition.
