The Lua runtime will allocate a table from the same memory pool whether the 
definition is made in a script or by C API calls. What you want to do is 
create userdata to allow scripts to access the message data in the C 
structures. You then have control over where that memory is allocated. You 
also save time by not copying data when dispatching the message.
