I have done this as I have commented before and there was a problem
where socket.lua did a require("lsocket"). This meant that if you pre loaded
the C library :- lsocket which actually imports into the "socket" 
namespace then
the lua code is never loaded. My fix to this was to import the C 
functions into
the "lsocket" namespace and assign the functions

socket.<x> = lsocket.<x>

when the socket lua module is loaded. Has the behaviour of the compat-5.1
module changed so that this no longer is a problem?
