/// MemoryStream implementation that deals with pooling and managing memory streams which use potentially large
/// buffers.
/// </summary>
/// <remarks>
/// This class works in tandem with the RecylableMemoryStreamManager to supply MemoryStream
/// objects to callers, while avoiding these specific problems:
/// 1. LOH allocations - since all large buffers are pooled, they will never incur a Gen2 GC
/// 2. Memory waste - A standard memory stream doubles its size when it runs out of room. This
/// leads to continual memory growth as each stream approaches the maximum allowed size.
/// 3. Memory copying - Each time a MemoryStream grows, all the bytes are copied into new buffers.
/// This implementation only copies the bytes when GetBuffer is called.
/// 4. Memory fragmentation - By using homogeneous buffer sizes, it ensures that blocks of memory
/// can be easily reused.
///
/// The stream is implemented on top of a series of uniformly-sized blocks. As the stream's length grows,
/// additional blocks are retrieved from the memory manager. It is these blocks that are pooled, not the stream
/// object itself.
///
/// The biggest wrinkle in this implementation is when GetBuffer() is called. This requires a single
/// contiguous buffer. If only a single block is in use, then that block is returned. If multiple blocks
/// are in use, we retrieve a larger buffer from the memory manager. These large buffers are also pooled,
/// split by size--they are multiples of a chunk size (1 MB by default).
///
/// Once a large buffer is assigned to the stream the blocks are NEVER again used for this stream. All operations take place on the
/// large buffer. The large buffer can be replaced by a larger buffer from the pool as needed. All blocks and large buffers
/// are maintained in the stream until the stream is disposed (unless AggressiveBufferReturn is enabled in the stream manager).
