    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.
