These DCHECKs involve reading and comparing two variables that may be modified on a separate thread. Thus, there is no way to ensure these comparisons happen atomically. This leads to runtime failures that are otherwise benign. The other option would be to take the memory tracker mutex, but this seems unnecessary given that two atomic counters is sufficient and these checks are only used during debug builds.
