Only those holding references to their threads well beyond the lifetime
of said threads. Is there a reason why that might be common?

If it really is a problem, though, then I wonder if keeping the exit
value on successful conclusion of the thread could be dispensed with.
Erlang doesn't do that, for instance. It'd still be useful to keep the
killing exception, if there is one, though.
