These patches start to add support for POSIX Shared Memory Objects, see http://pubs.opengroup.org/onlinepubs/9699919799/functions/shm_open.html This support aims to improve POSIX compliance.
The approach taken is to use the existing score Object as the basis for each shm object, where the Object.Name field directly relates to the name provided to shm_open(). So far the support for shm_open and ftruncate have been included. Support is needed for close() and shm_unlink(). A test is added based on some example code from an OS text book. This test also uses mmap() and munmap() which should be added to support mapping shared memory objects.
