I don't see how it's an objection. If you have a condition variable you
just use the cv's timeout feature, don't you? I guess there are already
tons of combinations which don't make sense anyway.

What do you mean by thread interruption? Cancellation?

Well, it's pretty basic functionality provided by the underlying OS
APIs, which is why I think it would be good to expose it. I remember
being annoyed by its absence, but it was a long time ago and I don't
remember which problem I was trying to solve.

(and it's safer than thread cancellation ;-))
