Young GlobalHandle nodes were processed during post processing which
required a logic to defend against recursive GCs. This was originally
designed in a delayed way as the list itself was only treated as an
optimization and could thus be lazily cleared.

Since this still happens in the atomic pause and every node needs to
be visited, there's no advantage over just keeping it correct at all
times.
