I've gathered some numbers (most recent commits last):

290def72f54db7969258b4541aaefc87b54ce448  44354749424  Implement warnings
for Semigroups as parent of Monoid

741f837d652fd00671614d52a6cb16fbc3758480  44489177576  Implement more
deterministic operations and document them

I've collected them on my machine and they differ from what harbormaster
reports, the last commit measured by harbormaster is 44728541608.

The target value is 40624322224 +/-10% and my numbers suggest it's been
steadily climbing out of that range. I don't know what this test measures
exactly, does it depend on the number of haddock comments in GHC's source?
