unfortunately, it only copies primitive values, not tables.
a somewhat more complete solution would be to use Pluto
(http://luaforge.net/projects/pluto/), to mangle a complex structure into a
string and then transfer that.
a nice optimisation would be to add new writer/reader functions to Pluto that
do the inter-state transfer. it still would be several copies, but might be
worth the try.
even better would be if lua_xmove() could work across separate states. of
course the naive implementation would hopelessly confuse the two garbage
collectors. maybe a full working interstate lua_xmove() would be as heavy as
