*	Don't write control file if content is not changed from previous one	Tatsuhiro Tsujikawa	2015-11-10	1	-0/+72
	This is desirable so that we don't have to wake up disk if control file is not changed, and it is not have to be written again. We use the same method (SHA1 hash) to check the content is the same. The limitation is the hash is stored in memory, so we have to write the first time in each session. See GH-382
