Volker Lendecke 275d9fc7d9 tdb: Fix mutexes on FreeBSD ...

susv4 on mmap has the following snippet:

> The state of synchronization objects such as mutexes, semaphores,
> barriers, and conditional variables placed in shared memory mapped
> with MAP_SHARED becomes undefined when the last region in any process
> containing the synchronization object is unmapped.

This means we can't keep the mutex mmap area unmapped at any point
in time.
