Review comment:
Yup! slf4j largely prevents this from being an expensive call (the pain
is often concatenating the strings together).
Thanks for looking!

Review comment:
Good question. Only because that's what every other log message in this
class does.
I'm guessing this was an attempt to consolidate RPC debugging to a single
class (when we had both NIO and Netty impls), but I'm not 100% sure.
