4 months ago - insured correct behaviour with SYSV shmmap (connect to an existing SYSV mapping via the OS_HANDLE, which is a number)
- mappings are now destroyed correctly on exit or with shmunmap, when permitted by defaults or positioning of the DESTROY_ON_EXIT keyword.
- tidying the shared mapping is performed on gdl exit, even if not specifically asked for using shmunmap.
- synchronisation of shared memory file contents should be better.
