1. File already have some bytes available in block. (ex: 1024B)
2. Re-open the file for append, (Here reserving for (BlockSize-1024) bytes)
3. write one byte and flush,
4. close()
After close(), releasing *BlockSize-1* bytes from reservedspace instead of
*BlockSize-1025* bytes.
Extra bytes reserved may create problem for other writers.
