   buffer.parent stores the parent Buffer instance when you call buffer.slice(), since slices reference the memory of the original buffer (no data copies are made). For new Buffers not originating from a slice, it's set to a chunk of memory from the pre-existing memory pool.

   Additionally, I believe it also helps with GC, so that when all slices of a particular buffer get GC'ed, the parent buffer can then be automatically and safely GC'ed.

   Note that undocumented properties are not something you can generally rely on in your code.
