is there test coverage for this change?

[ssid, 2016/01/08 11:26:01]

There doesn't seem to be any unittest for this function or GetPeakWorkingSet
api. So, the answer here is no.

I mean, is this path now taken while it wasn't before? Or are you removing the
NOTREACHED() just in case?

   return 0;
