Mike Percy commented on FLUME-1961:
-----------------------------------
My preference would be to start off adding this stuff to AbstractChannel, and
then over time after we feel it's quite stable we can create a channel
super-interface that has all that stuff in it. Interfaces are more formal and
less dangerous for implementers than abstract classes (when you add a method to
a base class you are stomping in your subclass's namespace) but we don't want
to end up with 5 different types of channel RTTI checks all over the place
either.
