Boost : |

I made the test with the CVS version of boost and I still fall in the
problem that I have reported some days ago :(
Btw I think that a bug in the Windows API GetQueuedCompletionStatus sounds
very strange to me because I think that implementations like this one are
very common or I'm wrong?

As reported in my previous message all handlers are invoked with the
params _1/_2 due to a multiple definition link error.
