[Pedro Alves]

Sorry, if I missed the discussion on it, but,

This is conceptually not right. gdb_thread_select is a libgdb
function, that filters exceptions.  If do_captured_thread_select
throws an error, you will still call the observer.  Plus, 
do_captured_thread_select is already printing the thread change
to MI, which means you'll get the output twice now, in MI?

Why not call the observer from inside do_captured_thread_select,
instead of on both CLI and MI commands?
