1740006 - Delayed gray marking happens before delayed black marking

Status: RESOLVED FIXED

(Core :: JavaScript: GC, defect, P3)

Description

[Jon Coppeard (:jonco)]

At the moment we mark children of gray cells in delayed arenas before black ones. This was because originally black entries had to live at the top of the mark stack (marking delayed arenas pushes stack entries here).

This is no longer the case, and it's possible that it is causing bug 1724599 where we are marking something gray that really should be black (the idea being that it would eventually be marked black but we're doing the delayed gray marking first). Therefore I'd like to change this to marking black first.
