If you can currently get away with a parser bound to each worker, then 
why does that need
to change when using asio?

I don't understand why you would have an objection to a permanent 
binding with TLS or
a temporary binding using a pool of parsers, since it seems that each 
datagram must be
parsed entirely and then the parser reset for the next? You said the 
parsers are stateful
but I don't see how that can be without a great deal of pain with UDP as 
a result of packet
loss or reordering.

Those receiver buffers are large for UDP. Are you expecting packets to 
survive fragmentation
reliably?
