This isn't a correct fix. The joinee (the thread being joined _to_)
is responsible for clearing the joiner's join_status.thread when
he detaches/exits. Threads in a join operation are allowed to
call signal handlers, so it needs to be in a loop (in theory, the
joinee could detach/exit while the joiner was running the signal
handler).
If there is a bug, it is in the exit or detach code.
