While that is a default, one can actually disable the Media Sensing:
One of the first google hits on disable media sense:
http://www.windowsnetworking.com/articles_tutorials/Disable-Media-Sense-TCPIP-Windows-XP.html
And voila, your connections keep open even if you change from wired to
wireless, as long as you get the same IP on both or if you unplug the
cable and plug it in a bit later etc.
Now if that works over sleep that is something I am not sure of, I
rarely let computers go into sleep mode (long live "NoSleep" on OSX).
Typically people who require that though will settle for the use of mosh
(http://mosh.mit.edu/) apparently.
