An interesting question might be ... what do you want to happen to such
data?  Do you want it mixed in with the stdout stream?

For an IProtocol-based API, there aren't a lot of other options.  Maybe it
would be useful to have a similar API that works in terms of
IProcessProtocol instead of IProtocol?

There is a ProcessEndpoint that takes a flag that controls what it does
with stderr - currently supporting only two options, log it or drop it.

What did you hook extReceived up to in your subclass?
