Made even more strange and bogus when you notice that in the unix domain
	rv = bind(s,sa,sizeof(sa));  /* yes, I know this is incorrect */
returns EINVAL even if the filename part of sa contains only valid
characters and '\0's (at least in SunOS 3.4).  4.3BSD doesn't complain,
though.  This one had some poor grad students on a Sun very upset
for a while: "But 0 has no high bits set!"
