Change subject: Make tcmalloc heap sampling more useful
......................................................................


Patch Set 2:

> Is that because it's macOS? If not, how does one read that?

You're telling me you can't symbolize addresses in your head?!

In that case you can use the pprof tool as follows:

./thirdparty/installed/uninstrumented/bin/pprof  build/latest/bin/kudu-master 
http://localhost:8051/pprof/heap

(or point it at a path to an already-downloaded heap profile instead of using 
HTTP if you collect one from some production server without the tool installed).

I believe there is also a newer version of pprof implemented in go, but I 
haven't tried that one. I think they moved towards protobuf-based dumps instead 
of text in recent years.
