Well yes, we can work around the hang by calling into Pango later,
after the workers have forked:
https://gitlab.com/lilypond/lilypond/-/merge_requests/688
However, memory usage is much higher than with 1.48.2 and I suspect
Pango is leaking: https://gitlab.gnome.org/GNOME/pango/-/issues/543

If you can, avoid 1.48.3 for now!
