 Good day.

 Boost::threads has example "conditions.cpp" in boost\libs\thread\example
 folder.

 This sample has problems with synchronyzation between output streams:
 {{{
 void sender() {
 ...
         std::cout << "sent: " << n << std::endl; // <-- There isn't
 synchronyzation
 ...
 }
 void receiver() {
 ...
         std::cout << "received: " << n << std::endl;  // <-- There isn't
 synchronyzation
 ...
 }
 }}}

 So the result of this sample looks like this:
 {{{
 received: 96
 received: sent: 97 // <--
 sent: 98
 sent: 99
 97 // <--
 received: 98
 }}}

 I think this is very strange for multithreads synchronization sample ;).
