Your approach and patch seem correct, but I worry about how old commands are processed.
Do I get it right, that replies to old non-bundle commands are queued back instead of sending immediately,
but since it is not bundle but single command, queued reply is being sent 'almost' immediately?
Basically, nothing changed to old clients, but there is new way to send batch requests now?

And please make indent less paranoid about line length, it is really hard to read some lines,
which were broken into pieces just because of that.
