- truss a simple program that creates threads and has them all die due
to a trap in one of the threads
(this does not log interrupted system calls when the threads are
killed by the kernel)
- truss a simple program that creates threads that all gracefully exit
(this logs thr_exit() calls)
- truss a simple program that forks a child process to regression test -f
- test attaching to the first two threaded programs while paused to ensure
all threads report events properly after the pause.
- truss a simple program that creates a thread and then calls exec to
ensure the implicit exit of the extra thread is logged
