> This patch is for Window platform only. In Windows platform, if there are
> more than one replicas writing to disk, the segment log files will not be
> consistent in disk and then consumer reading performance will be dropped down
> greatly. This fix allocates more disk spaces when rolling a new segment, and
> then it will improve the consumer reading performance in NTFS file system.
> This patch doesn't affect file allocation of other filesystems, for it only
> adds statements like 'if(Os.iswindow)' or adds methods used on Windows.
