Detailed Description

Returns the free pages of a device_pinned_pool to the OS when it leaves scope.

The pool keeps freed pages so work that allocates and frees pinned buffers repeatedly pins them once; a guard around that work keeps the process from holding them afterwards. A trim that fails only leaves the pages pinned, so its status is not reported.
