Several people mentioned that SYSVR3 does not
have sockets and I agree. I was thinking about
the socket packages that are provided by 3rd
party vendors. I am curious if they integrate 
sockets into the file system or write them as
a device driver.  If any of this is public domain
I am interested in acquiring the code.

However, SYSVR4 does have sockets based on streams
and I am curious how it maintains sockets for dup
and fork operations.
