N2184 takes the minimalist approach. It is easier to add functionality (and the associated expense) than to subtract it. There are many things the N2184::thread does not directly support. I believe this is a feature, not a bug.
This is true under the assumption that we need to target the least common denominator. Try/timed joins for example come for free on Windows. So you are imposing an unnecessary mutex+cv overhead for everyone wanting to use try/timed joins there.
I've decided to adopt a different approach and suggest a way to equalize ('harmonise' in EU terms :-) ) the platforms via the join2 extensions. In a perfect world, this would lead to everyone enjoying _zero overhead_ try/timed joins in a few years once pthread implementors adopt the extensions.
That would be good, even if thread joining probably (hopefully) isn't where applications spend most of their time. / Johan
