Comment (by lumosimann@…):

 We now found a temporary fix for this problem. Please check

 https://gist.github.com/lukasm91/9732228f33e92963bb8762dac519e79f


 Note that there are two bugs involved, one in sleep_for, and one in
 try_join_for. We found two functions where a differentiation between
 monotonic and non-monotonic time was missing, such that some functions
 always used monotonic, and others always used non-monotonic time.

 There is also an updated test file attached. Consider that when you
 undefine
 BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC, this currently needs to be
 done in libs/thread/src/pthread/thread.cpp too, otherwise the compiler
 won't find the correct template specialization. The old behavior can be
 reactivated by undefining USEFIXES.

 @viboes Could you please check this fix and incorperate it into boost? We
 know that most probably a few #ifdefs are missing, but this fix currently
 solves our problems.
