Review Comment:
Avoid getting into infinite recursion if there is a temporary memory
allocation in mem_tracker.consume/try_consume.
It is mentioned in the comments of `tcmalloc_hook.h`: Allocating memory in
the Hook command causes the Hook to be entered again, infinite recursion.
This needs to ensure that all memory allocated in
mem_tracker.consume/try_consume is freed in time to avoid tracking misses.
