Ok good start. Let's add more things in the queue (or split it into
separate tests) to show that:
- realtime signals are ordered properly
- you can queue more than one realtime signal
- don't use sighold/sigrelse. these are obsolete and release
only one signal at a time. use sigprocmask (plus since you are
releasing them one at a time, the release order is the order
you are going to see them delivered.
Then we can turn it into an ATF test.
