Tracing allocators of virtual memory and main memory

[SAHIL]

Hi Nicholas

Yeah right, pidstat which read /proc gives me VSZ ans RSS but i need to backtrace when VSZ/RSS is high which indicates process is allocating memory which it is not even using. 

And to modify the question i need to analyze allocations per thread, using /proc will it will also include VSZ RSS of parent.?
