Yes, likely until a thread-join has happened. And a second thread-join
on the same thread shall always return ni.
How long do we keep the results of dead threads, for which no
thread-join happens? Do we need a Lisp cleanup function, which purges
all dead threads results? Or does this the GC, when no Lisp object holds
the dead thread any longer?
(Btw, I believe it will be much better when you implement this. It is
still hard for me to read and modify threads.c)
