I might be misreading this, but I believe that threads->object() ignores
detached threads unless a tid is explicitly passed in *and* that tid is the
tid of the calling thread. The main thread is detached, so no thread other
than tid 0 can look it up via object().
(You describe an interesting problem and approach; do you have
demonstration code that others can take a look at?)
