[OpenSmalltalk/opensmalltalk-vm] AARCH64/ARM64 OSProcess forking crashes VM immediately (Issue #681)
OSProcess includes a neat way to fork the running image/vm but unfortunately it doesn't work on arm64 (at least, not on a Pi3/4/5).
We had some discussion about this a while back (sorry, not written notes I can find) and I think we concluded it was likely to do with the setup for the dual-access of the translated code memory area not getting carried across with the fork.
