sorry if I wasn't clear. since this is part of ChildProcessHostDelegate, this
belongs on line 93 right after OnChildDisconnected. Move that entire block (i.e.
now line 90-95) to the public section

Ah, I see.  We'll just make the whole implementation public.  Done, added those
here right under the implementation of BrowserChildProcessHost.

 
   // Removes this host from the host list. Calls ChildProcessHost::ForceShutdown
   void ForceShutdown();
 
   // Callers can reduce the BrowserChildProcess' priority.
   void SetBackgrounded(bool backgrounded);
 
   // Controls whether the child process should be terminated on browser
   // shutdown. Default is to always terminate.
   void SetTerminateChildOnShutdown(bool terminate_on_shutdown);
