Here's a problem Google can't answer. I'm doing some HTTP "long polling" with XMLHttpRequest for a multiplayer game. In Chrome, this causes the tab to always be "loading" : (1) the icon in the tab is constantly playing the loading animation (2) the cursor is constantly an hourglass (3) the status persists forever at the bottom of the view area saying "contacting localhost"
I was sure others have run into this, but I can't find them yet.
