Re: [boost] [thread] Interaction between interruption points and condition_variable

That means cv.wait() is only an interruption point under certain circumstances.

cv.wait is already only an interruption point only if the predicate is false to begin with. My preferred behavior would, in some ways, maintain that relationship. If you make the predicate true and signal, then interrupt, and the user has not yet begun to wait, they will encounter a true predicate and never be interrupted. If they have begun to wait (under the current behavior), it is undefined whether they will be interrupted.
