This is very, very sad. 
I intentionally made this thread local so that we don't use atomics in a very hot place (and malloc is often a very hot place). 
Besides, I am only collecting counts from the main thread. 
Need to find another solution, e.g. to not touch AllocTracer before we called Start() on it.
