Regardless of how many times a process locks a page, a single will unlock it. When memory is shared by multiple processes and mlocks are applied to the same physical page by multiple processes, a page remains locked until the last lock is removed from that page.

Processes owned by other users may have this privilege, depending on system configuration.
