Actually, I strongly suspect that the problem you are seeing was 
introduced in this changeset:

    http://divmod.org/trac/changeset/13798

Specifically, sendCloseMessage now sends a synchronous XMLHttpRequest as 
the page is shutting down.  Perhaps something about that is causing IE7 
to choke.

I don't have IE7, but I'd be very interested to hear if you can track 
this down.  Please feel free to submit patches which change the way that 
the reliable message delivery channel is torn down, if you can discover 
a better way.
