 Right.

 before returning false.

 Well, this is not what the documentation says :(

 try_join_for(0).

 Have you tried try_join_for(nanoseconds(1))?

 > Is there a reason why there is no try_join() function ?

 I don't know of a portable way to implement it.


 Please see #9618 and if you are on Windows, please could you check if the
 proposed patch works for you.
