Review comment:
       Ideally, the C# layer would have access to the DataInput and DataOutput 
buffers via the Region. However, this would likely require moving too much 
buffer management code to C#. An alternative that might be worth consideration 
is to have an interop buffer in the C++ heap (an std::vector), and give C# its 
address. This could be created during the cache create and deleted when the 
cache is closed. Always passing the length(s) of interop parameters would allow 
growing the buffer as needed.
