You're grasping at straws.  There are speed vs space trade-offs in
everything, and bigger systems always choose speed.  If you want
something that saves space over CPython, try MicroPython.  It uses a
mark-sweep GC (I don't remember if it relocates) instead of semispace.

Hedgehog Lisp (not used much these days) was designed to run on
microprocessors with around 256K of memory and it used a semispace GC
(it actually had semispace and mark-sweep).  256K is probably still too
small for CPython.

If you want REALLY tiny, there is a Boehm-style conservative GC
available that's written in Forth for use in Forth systems.

What's the smallest memory system that you've used CPython in?  What's
the largest Python heap you've had to use?

I once slapped together a CPython script that had around 50GB of live
data memory (it scanned a TB or so of server logs and collected some
info by tracking stuff that had been seen earlier and was kept in
memory) but again that was a speed-space tradeoff.  If it had used 100GB
or even 200GB I wouldn't have cared, since I had a 256GB machine
available to run it on.

On the other hand if all I'd had was say an 1GB machine, I would have
written the script differently to make two passes separated by an
on-disk sorting phase.  I've done that type of thing many times.

I don't understand this notion of partisanship for reference counting.
Or even for CPython which is in many ways a crappy program that still
exists mostly because of a big legacy codebase that depends on it.  In
fact the reference counting is part of the problem because C extensions
have to deal with it.  Lisp and Java systems usually have a much cleaner
FFI where it's easier to port extensions between systems.
