SG1 recommends: Close as NAD
The approach suggested there raises all sorts of issues about thread_locals, etc. It's probably way too late to change this anyway, but this would have required a careful paper.[ LEWG Kona 2017 ]
Recommend NAD: (N4618 numbering) 30.5.1[thread.condition.condvar] p10.3 allows spurious wakeups. This issue is out of date.
[ 2010 Batavia ]
The Concurrency subgroup reviewed the issue, and deemed it an extension to be handled after C++0x.
The LWG does not wish to make the change at this time.
[ Resolution proposed by ballot comment: ]
Change condition_variable to allow such optimization. See Appendix 1 - Additional Details
Addresses US-193
Condition variables preclude a wakeup optimization.
