I fixed the bug related to non-null memory segment. The bug was caused by
non-clearing `writeBehindBuffersAvailable` variable in `close()` method of
`MutableHashTable` class. I added a test case for this bug.
I have a problem for creating a test case to test the bug related to null
memory segment. I think that it is related to parallelism also. If I run
ConnectedComponents example with parallelism 1, the bug not occurs. So I cannot
reproduce the state without ConnectedComponents example.
