I'm experiencing an odd phenomenon when using Boost ASIO 1.46.1.  (I know it's older, but this was inherited.)

Under normal operation, everything is fine.  I can create a TCP server socket, listen, and accept as expected.  If I disconnect the TCP client gracefully, everything resets as expected.

However, if I physically remove the network interface -- such as yanking the USB adapter out of its socket -- the TCP session stills reports as ESTABLISHED via netstat and the application receives no read error.

I'm at a bit of a loss how this is possible when the underlying OS shows that the interface no longer exists yet the socket is blocking away happily.  Has anyone else experienced similar symptoms?  Any advice?

Thanks in advance,

Chris
