Could I get more informations about strands, please?

There's a small section on strands in the TR2 proposal: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2054.pdf See also the fifth part of the timer tutorial: http://asio.sourceforge.net/boost_asio_0_3_7/libs/asio/doc/tutorial/tuttimer... and maybe the performance tests: http://asio.cvs.sourceforge.net/asio/asio/src/tests/performance/ Cheers, Chris
