Modified files:
sys/sys fcntl.h unistd.h
sys/vm vm_mmap.c
Log:
Implement POSIX.1b shared memory objects. In this implementation,
shared memory objects are regular files; the shm_open(3) routine
uses fcntl(2) to set a flag on the descriptor which tells mmap(2)
to automatically apply MAP_NOSYNC.
Not objected to by: bde, dillon, dufault, jasone
