#12519: boost::thread::try_join_for does not return after timeout
------------------------------+----------------------
 Reporter:  mweb@…            |      Owner:  anthonyw
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  thread
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------
 If we use BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC try_join_for does
 not abort after the given timeout anymore. If I remove the define it works
 again.

 We use the define to be able to use sleep_for while changing the system
 time. (See #6787)

 To Reproduce:

 {{{

 #define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

 #include <iostream>
 #include <boost/thread.hpp>

 void test_func()
 {
     boost::this_thread::sleep_for(boost::chrono::milliseconds(1500));
 }

 int main()
 {
     boost::thread t(test_func);

     if (!t.try_join_for(boost::chrono::milliseconds(50))) {
         std::cout << "OK" << std::endl;
     } else {
         std::cout << "FAILED" << std::endl;
     }

     if (t.try_join_for(boost::chrono::milliseconds(2000))) {
         std::cout << "OK" << std::endl;
     } else {
         std::cout << "FAILED" << std::endl;
     }
 }

 }}}

 If the define is available the first try_join_for waits till the thread is
 finished, the expected behavior would be that the first try_join_for would
 return before the thread is finished.
