This can be done much simpler on some Systems with a poor implementation
of shared memory:
- create a shared memory segment.
- do a shmat() on that segment.
- do a write(1,"foo",3)
The manual says: "never do systemcalls with attached shared memory",
but crashing the machine in such a case is much more poor than this
restiction.
