Even though the patch is correct, the results will not be. PHP's memory manager is quite unreliable for when it frees up memory. I don't quite know whether I want to add something that I know will confuse people...

This helped me to see most memory used, optimize, etc.

It actually doesn't matter for me to see correct numbers - when debugging memory usage all you need is allocations and percentage of total usage.

I do agree with atis, memory is important even if the numbers are not correct. That's a feature I've been waiting for a few years now, a profiler without memory information is only half-complete.
