[Tom Sepez, 2015/02/18 23:49:53]

do we want to set exit_code to some impossible value and then EXPECT that
WaitForExitWithTimeout set it to something reasonable?

[rvargas (doing something else), 2015/02/19 02:01:04]

I have no idea what an impossible (or reasonable) value would be.

I can EXPECT that to be 0 if you want me to, and see if the bots are happy with
that... I just don't see how this layer can predict what the exit code would be
or how a zero exit code (or anything) is implied by the contract of
WaitForClientShutdown()

Let me know what you want me to do.

+  bool rv = client_process_.WaitForExitWithTimeout(
+                base::TimeDelta::FromSeconds(5), &exit_code);
   client_process_.Close();
   return rv;
 }
