    [heap] Support fixed arrays with progress bar in the concurrent marker · 7ca8acd0
    Ulan Degenbaev authored
    Currently the concurrent marker visits any fixed array in one go
    ignoring the progress bar and does not expect seeing black arrays
    in the worklist. For this reason, if the main thread marker starts
    visiting a large array with the progress bar, then it has to re-push
    the array in the bailout worklist. So all subsequent visitations of
    the array happen on the main thread.
    
    This patch makes the progress bar thread-safe and allows the
    concurrent marker to visit arrays in chunks.
