Waiman Long d26bf5056f debugobjects: Reduce number of pool_lock acquisitions in fill_pool() ... In fill_pool(), the pool_lock is acquired and then released once per debug object. If many objects are to be filled, the constant lock and unlock operations are extra overhead. To reduce the overhead, batch them up and do an allocation of 4 objects per lock/unlock sequence.
