A lot of these issues should be fixed in test8-pre2. It does more of a true job of having shared signals instead of emulating them with a global "blocked" list and spreading them out to be local signals.
I looked at test8-pre2, and the basic strategy looks promising :-).
However folding CLONE_SIGHAND and CLONE_THREAD onto CLONE_SIGNAL doesn't work. The current LinuxThreads library uses CLONE_SIGHAND but cannot deal with the thread group stuff (it relies on getpid() returning the process ID of the thread and not the process ID of the thread-group leader). Basically locks up every existing multi-threaded program.
