> Fetcher doesn't log it's stdout/stderr properly to the log file

> The fetcher doesn't log it's stdout or stderr to the task's output files as 
> it does on Linux. This makes it extraordinarily difficult to diagnose fetcher 
> failures (bad URI, or permissions problems, or whatever).
> It does not appear to be a glog issue. I added output to the fetcher via cout 
> and cerr, and that output didn't show up in the log files either. So it 
> appears to be a logging capture issue.
> Note that the container launcher, launched from 
> src/slave/containerizer/mesos/launcher.cpp, does appear to log properly. 
> However, when launching the fetcher itself from 
> src/slave/containerizer/fetcher.cpp (FetcherProcess::run), logging does not 
> happen properly.
