Within reason, that is.  There is a limit to how many things you can 
push on the stack.  You need to call lua_checkstack if you want to push 
lots of stuff on the stack.  And even lua_checkstack has a limit.

/* minimum Lua stack available to a C function */
#define LUA_MINSTACK	20

/* maximum size for the C stack */
#ifndef LUA_MAXCSTACK
#define LUA_MAXCSTACK        2048
#endif
