Extend dsm API with a new function dsm_unpin_segment. If you have previously pinned a segment and decide that you don't actually want to keep it around until shutdown, this new API lets you remove the pin. This is pretty trivial except on Windows, where it requires closing the duplicate handle that was used to implement the pin.
