Just to point out, this is hard to write test for. The best you can do is create cache, fill it, drop it and repeat. The offheap memory usage raises. I've been testing this patch for 2months now on our machines and it seems effective.

> H2 Indexing unregisterCache method does not call TableDescriptor's GridH2Table close and optionally GridLuceneIndex close, which causes OFFHEAP_TIERED cache to leak memory.
