You could write some accessors/setters for the "global"
environment in C and then bind them to lua so that the code can
be called by the different threads when they're running in lua
mode. Just make sure the C code is re-entrant and that you
synchronize access to the meta global environment.

It's very possible but lua in itself, as far as I can tell, does
not facilitate this transparently in anyway. You need to do it
yourself.
