-// When running a plugin in a different process from the renderer, we need to
-// proxy calls to NPObjects across process boundaries.  This happens both ways,
-// as a plugin can get an NPObject for the window, and a page can get an
-// NPObject for the plugin.  In the process that interacts with the NPobject we
-// give it an NPObjectProxy instead.  All calls to it are sent across an IPC
-// channel (specifically, a NPChannelBase).  The NPObjectStub on the other
-// side translates the IPC messages into calls to the actual NPObject, and
-// returns the marshalled result.
