#12949: using sleep_for in a thread context without including
boost/thread/thread.hpp yields incorrect behaviour when
BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC is defined
----------------------+------------------------------
 Reporter:  rkaris@…  |       Type:  Bugs
   Status:  new       |  Milestone:  To Be Determined
Component:  None      |    Version:  Boost 1.63.0
 Severity:  Problem   |   Keywords:
----------------------+------------------------------
 When defining a function f() in a compilation unit which uses
 boost::thread::sleep_for() which does not include
 <boost/thread/thread.hpp>, but another boost thread header,

 function.h
 {{{
 #ifndef FUNCTION_H
 #define FUNCTION_H

 void f();

 #endif
 }}}

 function.cpp:
 {{{
 #define BOOST_THREAD_VERSION 4
 #define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

 #include <boost/thread/condition_variable.hpp>

 #include "function.h"

 void f()
 {
     boost::this_thread::sleep_for(boost::chrono::milliseconds(10));
 }
 }}}

 and defining a compilation unit which uses this function in a thread
 context,

 main.cpp:
 {{{
 #define BOOST_THREAD_VERSION 4
 #define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

 #include "function.h"
 #include <boost/thread.hpp>

 int main()
 {
     auto t = boost::thread([]
     {
         f();
     });

     t.join();

     return 0;
 }
 }}}

 the sleep_for() waits much long than expected when a monotonic clock is
 used.

 This has been tested with both boost versions 1.63.0 and 1.64.0 beta2.
