I'm not sure I would recommend that in general any more. A long-lived 
(weak) table can grow pretty large if at one point it has lots of 
entries, and will stay that way until it is garbage-collected. See the 
recent thread on "table.new in 5.3".

p.s.: The function is called `lua_setuservalue` not `lua_setusertable`. 
Just saying ...
