Well really the _best_ way IMO is to both comment and submit a patch. ;-)
And this is just what Thomas is doing, so kudos to him for the effort!
Vishal is doing this as well for many of the issues he's found, so thanks to
him also. We do appreciate you guys jumping in to help. Lack of contributors
is one of the things we've been missing and addressing that opens the door
to some of these improvements being suggested.
Wrt the netty patch, the approach Ben and I took was to refactor
sufficiently to add support for NIO/Netty/... while minimizing breakage.
This is already a big patch, esp given that the code is not really as clean
to begin with (complex too). Perfect situation, no. But the intent was to
further clean things up once the original patch was reviewed/committed.
Trying to do a huge refactoring in one shot (one patch) is not a good idea
imo. Already these patches are too large. Perhaps lesson learned here is
that we should have just created a special branch from the get go, applied a
number of smaller patches to that branch, then eventually merged back into
the trunk once it was fully baked.
