---------------------------------------------------+------------------------
 Calling the this_thread::sleep_for() results in a sleep almost twice as
 long as desired.

 code:
 {{{
 #include <iostream>
 #include <boost/thread.hpp>

 int main(int argc, char * argv[])
 {
   boost::chrono::system_clock::time_point start =
 boost::chrono::system_clock::now();
   boost::this_thread::sleep_for(boost::chrono::seconds(1));
   boost::chrono::system_clock::time_point end =
 boost::chrono::system_clock::now();
   std::cout <<
 (boost::chrono::duration_cast<boost::chrono::microseconds>(end -
 start)).count() << std::endl;
   return 0;
 }

 }}}

 When built in MS Windows 7 x64, the program outputs
 2000114

 The same code in linux x64 outputs
 1000298
