Todd Lipcon resolved KUDU-1953.
-------------------------------
Resolution: Fixed
Assignee: Todd Lipcon
Fix Version/s: 1.4.0
In 2be32d5441827e0914ad9b5008545003bfda4575 I decoupled the root memtracker
from tcmalloc, and made the throttling depend directly on tcmalloc. So, the
root tracker is just a simple sum of its descendants, but mem rejections should
be accurate.
> MemTracker root tracker consumption is rarely updated
