Milestone:  To Be Determined                     |  Component:  thread
  Version:  Boost 1.54.0                         |   Severity:  Problem
 Keywords:  win32, thread, condition_variable,   |
  wait_until                                     |
-------------------------------------------------+-------------------------
 on win32 platform {{{ condition_variable::wait_until(lk, t) }}} can wait
 infinite long if
 {{{
 #!cpp
 ceil<milliseconds>(t - t::clock::now()).count() == -1
 }}}

 do_wait takes boost::detail::timeout. It constructs from -1 =>
 boost::detail::timeout::milliseconds == 0xf..ff, witch is a special value
 checked by is_sentinel().

 Later in win32/thread.cpp: this_thread::interruptible_wait code waits
 boost::detail::timeout::max_non_infinite_wait.

 tested it with msvs 2010.
