Note that a child doesn't handle an entire transaction. It can occurs, and 
it's the most probable, that the reply is handled by other child.

Also the childs don't manage transactions but transport level connections (or 
UDP datagrams). This is: a child can receive a request, process it, create 
branches and send them, and after it,  the child can receive other different 
request over the same TCP connection and manage it without waiting for the 
previous transaction finished (note that an INVITE transaction can be alive 
more than 1 minute).

So I think you are wrong when associate "childs" and "transactions". It's more 
correct if you associate "childs" and "connections"/"datagram arrival".
