I've run some additional tests, mostly pgbench with
options=-cjit_above_cost=0 for an extended duration on an instance
that was impacted. I haven't seen any issues nor performance
regressions compared to the unpatched version.

I will switch the commitfest entry to Ready for Committer if there's
no objection.
