lua_dump is used by lanes to copy the function from one Lua VM to another independent VM. The function in the source Lua VM is dumped, then the generated buffer is loaded in the target Lua VM to create a function, and upvalues are copied too. I'm pretty sure this can't be done differently using the public API.

If the provided "function" is in fact a string, Lanes could probably either "luaL_loadfile" or "luaL_loadstring" it directly in the target Lua VM. This has the advantage that there are no upvalues to be taken care of. I'll have a look at it, just in case it is easy to do.

But this doesn't solve the fact that Lanes won't work with regular functions if the VM's implementation doesn't support lua_dump.
