That's why we tend to test for MTU and then stay below it, with the
generally safe (and blind) guideline being 512 bytes total. This is 
pretty small, but control and status update messages tend not to be
anywhere near this large in practice. Reliable transfer of data has
to happen on a separate TCP connection, perhaps created in response
to a UDP control message.
