    Allow mocking the limits for ArrayBuffer allocation to simulate operating
    system OOM.
    
    Fixes:
    - Ensure OS limit > hard limit for external memory. This is necessary as
      any processing below the hard limit is opportunistic. E.g. a running
      sweeper may stall the current marking (GC) round.
    - Immediately process AB allocations when under memory pressure. Otherwise,
      the allocations may be stuck in a stalled task. Freeing them upon
      adding them to the collector still enables parallelism if possible.
    
    This reverts commit f3ad6cdb.
