R devel - May 2008 - closeAllConnections fails with socketConnection (PR#11396)

If a socketConnection is created in an R session, and you call
closeAllConnections to close it, you get the following error:
> x <- socketConnection("localhost", 80)
> closeAllConnections()
Error in socket$socket : $ operator is invalid for atomic vectors

You get the same error message if you try to quit, saving the
workspace image.

I also noticed that getConnection returns an object that has a
different class than the original socket connection object:
> class(x)
[1] "sockconn"   "connection"
> class(getConnection(3))
[1] "socket"     "connection"
