I should have skimmed ahead in my mailbox; your RFR is already available in preliminary form.

I’d forgotten how much bootstrapping clunkiness was needed for 8214097 without this change.
So yeah, looks like doing mine first does help yours.

Looking at yours, I kind of want the remaining bootstrapping in mine to use your change to set_as_starting_thread,
(e.g. use your new _starting_thread to recognize it), except I think that function is called too late to use for that purpose.
