Does 'code from 4.2 BSD' mean snippets of actual kernel code or more 
like examples of BSD-specific syscalls and networking (socket(), select())
and such?

In the latter case you could see if you can still get a copy of the old 
(1986) book 'C Programming in the Berkeley Unix Environment' which was pretty 
much filled with BSD specific stuff and how that was perhaps done in 
attributing the correct parties:

Unfortunately my copy got lost over some moves, so I no longer have one
to look it up...
