> When initial block reports are being processed, checkMode() is called from
> incrementSafeBlockCount(). This causes the replication queues to be
> initialized in the middle of processing a block report in the IBR processing
> mode. If there are many block reports waiting to be processed,
> SafeModeMonitor won't be able to make name node leave the safe mode soon. It
> appears that the block report processing speed degrades considerably during
> this time.
