Update: I created a blog post for this solution. Any feedback is welcome!

I recommend using the 'sync disconnect on unload' option for Socket IO. I was having similar problems, and this really helped me out.

On the client:

var socket = io.connect(, {
'sync disconnect on unload': true });

No need to wire in any unload or beforeunload events. Tried this out in several browsers, and its worked perfectly so far.
