I believe I was able to understand what you were doing here :) Seems ok. The assumption above looks a bit risky without any way to enforce it. Perhaps you could make in_use private (renaming to, say, m_in_use) and add an inline getter method TABLE::in_use() that in debug builds will assert that your assumption holds?
