+class CSubSessionIx
+This sub-session container will maintain its own array of TEntry cells in memory as arrays provide for
+quick access in some situations. There will be two types of cells in the array; cells carrying pointers
+to sub-sessions and a virtual list of free cells.
+This layout means that with a handle, the entry holding the sub-session can be looked up in the container
+directly and if needing to insert a new entry the first free cell is indicated by iFreeListHead.
+The array will grow with EIndexGranularity each time it runs out of free entries. However, it maintains a high
+watermark and will never shrink.
+The handles are defined by TSubSessionHandle, which in the current architectures is a 32 bit word, constructed
+as needed. It is simple to deduct from the context so there is no need to store it.
