 From what little I have read about sociomantic's codebase 
(pre-allocated lumps of memory, stomped all over to keep code 
simple and prevent needing extra allocations, am I right?), I 
would imagine you would be better off just emulating the old 
behaviour in a little wrapper around a builtin array.
