I do not have access to a copy of POSIX and the SuSv2 seems to have
SHM support. Changing it to use say a UNIX socket would allow for
simpler packet design. Up to six bits for the version another two for
leap second status and then an octet for precision. Then the body
which could be a pair of timestamps. Then possibly refclock and
hostname overriding text fields.
