Details:
I've noticed joining games and returning from games to the lobby slows over
time. In the latest case, 8 hours continuous connection to the 1.6 MP server
resulted in 30+ second delay (at 100% CPU usage) to redisplay the lobby.
I've believe that the delay is approximately proportional to the quantity of
chat displayed in the textbox, and that the entirety of the texbox is
regenerated when joining a game, creating a game, returning from a game and
returning from the preferences dialogue. The effects of this become notice
after a hundred or so messages.
Following is a backtrace during the delay:
