The GDB core has a list of threads.  Until recently, a single-threaded
program would usually have no threads in the list (though in some
cases, there would be a single thread).  This makes it difficult to
keep track of per-thread state in a uniform way; state that a
single-threaded program should have one copy of but a multi-threaded
program should have one copy per thread.

No notifications should be displayed; that's because Pedro used
add_thread_silent and delete_thread_silent.
