How does this handle garbage collection? AFAIK the WebAssembly GC proposal is still in development. Does it implement GC in WASM code?

[amelius]

Perhaps it just uses Python's built-in garbage collector that just increases/decreases the data segment size as needed by calling sbrk()?

Correct, it is just CPython compiled to Wasm (similar to compiling to x86 or arm)
