I wonder why this SPLICE_F_GIFT option isn't the default. Surely the physical page can be mapped out of the process and another provided in its place, either on-demand or immediately. If the latter, and it's never written to, it remains clean and can be unmapped at need and used for something else if memory gets tight.
