I've reached the limit of how much time I can spend on this for now... 
But I implemented the string GC as Dave outlined. But, it doesn't work. 
Or I should say, it does work, but errors during one of the GC cycles 
with assertion failures in the GC code. Since this happens reliably for 
me inside the var expansion code, I suspect there's a buffer overrun in 
the variable expansion code :-(

So if anyone has the time, it would be nice to hook in, the same the GC 
allocator is, a debug allocator like dmalloc.
