Also to be sure that all before barrier is on disk, many test cases about
recovery rely on the fact that operations before barrier are on disk. This
is important with HARD failure case especially, without sync before
barrier the operations before barrier may be lost and affect the tests.
I agree that syncless variant of barrier is needed but we also need
barrier with sync depending on test case.
