 ///////////////////////////////////////////////////////////////////////////////
 //
 // BrowsingInstance class
 //
 // A browsing instance corresponds to the notion of a "unit of related browsing
 // contexts" in the HTML 5 spec.  Intuitively, it represents a collection of
 // tabs and frames that can have script connections to each other.  In that
 // sense, it reflects the user interface, and not the contents of the tabs and
 // frames.
 //
 // We further subdivide a BrowsingInstance into SiteInstances, which represent
 // the documents within each BrowsingInstance that are from the same site and
 // thus can have script access to each other.  Different SiteInstances can
 // safely run in different processes, because their documents cannot access
 // each other's contents (due to the same origin policy).
 //
 // It is important to only have one SiteInstance per site within a given
 // BrowsingInstance.  This is because any two documents from the same site
 // might be able to script each other if they are in the same BrowsingInstance.
 // Thus, they must be rendered in the same process.
 //
 // If the process-per-site model is in use, then we ensure that there is only
-// one SiteInstance per site for the entire profile, not just for each
+// one SiteInstance per site for the entire browser context, not just for each
 // BrowsingInstance.  This reduces the number of renderer processes we create.
 // (This is currently only true if --process-per-site is specified at the
 // command line.)
 //
 // A BrowsingInstance is live as long as any SiteInstance has a reference to
 // it.  A SiteInstance is live as long as any NavigationEntry or RenderViewHost
 // have references to it.  Because both classes are RefCounted, they do not
 // need to be manually deleted.
 //
 // Currently, the BrowsingInstance class is not visible outside of the
 // SiteInstance class.  To get a new SiteInstance that is part of the same
 // BrowsingInstance, use SiteInstance::GetRelatedSiteInstance.  Because of
 // this, BrowsingInstances and SiteInstances are tested together in
 // site_instance_unittest.cc.
