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.
