the docu says that c closures cannot share upvalues, see here:
http://www.lua.org/pil/27.3.3.html

"Unlike Lua closures, C closures cannot share upvalues: Each closure has
its own independent set. However, we can set the upvalues of different
functions to refer to a common table, so that this table becomes a
common place where those functions can share data."
