请教关于CreateNewSegment

[egb2000]

您好，_buffers.Count > _segmentChunks / 2 是表达什么意思？ 怎么觉得不需要这条过滤呢？

` private void CreateNewSegment(bool forceCreation)
{
if (!_allowedToCreateMemory)
throw new UnableToCreateMemoryException();

        lock (_creatingNewSegmentLock)
        {
            if (!forceCreation && _buffers.Count > _segmentChunks / 2)
                return;

            var bytes = new byte[_segmentSize];
            _segments.Add(bytes);
            for (int i = 0; i < _segmentChunks; i++)
            {
                var chunk = new ArraySegment<byte>(bytes, i * _chunkSize, _chunkSize);
                _buffers.Push(chunk);
            }
        }
    }`
