Initialize the convertor on _START not on _INIT. This allow us to

Просмотр исходного кода 
set it up before the match when we know the peer, saving some
time on the critical path. If the receive is ANY_SOURCE then
we initialize the convertor on _MATCHED. Anyway, we will set it
up only once per receive.
