Opengroup got that far:

        "If fildes refers to a socket, write() shall be equivalent to send() 
no flags set."

I take it, though, that you mean our implementation asserts conformance
with SuSv3?  It's easy to document what these things are supposed to do;
it's hard to know exactly what's true about them.  

I missed that announcement at the time.  IIUC, we can use opengroup's docs
verbatim?  That would be nice, particularly if they're in a format that is
or can be converted to mdoc.  Where are they?  

I'm confused about SuSv3, though.  Austin says it was approved in December
and is published by TOG.  I registered, yet everything I see at says "The Open Group Base
Specifications Issue 6 IEEE Std 1003.1, 2004 Edition".  Not 2008.  

Perhaps we should adopt the opengroup socket API docs wholesale and edit
them for any specifics we already mention.  Then we can add to the BUGS
section whenever practice deviates from theory until a kernel hacker
narrows the difference.
