This is a 4% slowdown, on a RAM-bound (not even CPU-bound) benchmark!

I do not see at all how this is even considered to possibly be acceptable, 
all the more for a feature intended to help improve performance (because 
that is really the only ultimate aim of improving profiling support, or what 
else would you want to do profiling for?).

No amount of profiling will allow recovering those 4% lost performance on 
any real-world software.
