Given that the implementation of Unix domain sockets normally pass
womping 108 byte path strings (see Richard W.  Stephens TCP/IP
Illustrated Volume 3 or the 'sockaddr_un' structure) with each message
a few extra bytes of overhead won't matter very much.

Small packets are likely to be smaller than the address. :-)
