Freeing resources associated with a user-supplied allocator

[Matt Campbell <mattc@...>]

Hello:

One apparently missing feature in Lua's user-supplied allocator support 
is a way for the allocator to be notified when it's already needed, so 
it can free associated resources.  For instance, on Windows, if I write 
a function that creates a new heap, then creates a new Lua state with an 
allocator which uses that heap, then it seems that I have to keep a 
pointer to that heap and free it myself after calling lua_close.  Is 
this correct, or is there a way my allocator can determine when it's no 
longer needed?  Thanks.
