Why are you inlining this destructor?

[gavinp, 2012/04/26 23:55:39]

It's against the style guide, even.  Fixed.

+                      const GURL& url,

Nit: Remove extra newline.

[gavinp, 2012/04/26 23:55:39]

Done.

+  const int render_process_id_;
+  Profile*const profile_;

[cbentzel, 2012/04/24 15:42:59]

spaces please. I haven't really seen use of *const in the codebase but it does
seem appropriate.

[gavinp, 2012/04/26 23:55:39]

Done.  I'm a fan of making strong statements with const where you can.  It's
when you start seeing const_cast<> that I am willing to talk compromise...
