what happens if OnChannelError() is called?  channel_ will be reset and this
filter will be deleted.  so if you want to hold a pointer to it, use a
scoped_refptr

[Bernhard Bauer, 2011/03/29 19:26:58]

I guess I should set the pointer to NULL in OnChannelError() then? I don't want
to hold on to the old ResourceMessageFilter after the channel is closed.
