-// The hypothesis at #55 requires that RemoveRoute() be called between
-// sending ViewHostMsg_OpenChannelToPlugin to the browser, and calling
-// GetPluginChannelHost() on the result.  This code detects that case
-// and stores the backtrace of the RemoveRoute() in a breakpad key.
-// The specific RemoveRoute() is not tracked (there could be multiple,
-// and which is the one can't be known until the open completes), but
-// the backtrace from any such nested call should be sufficient to
-// drive a repro.
