What's the problem? If we equip the server with HTTP keepalives then  
then the subsequent XMLHttpRequest should reuse the socket from the  
previous request. All we've got is several thousand persistent  
sockets connected to a listening process on a server. It's the same  
sort of engineering challenge ejabberd has in trying to keep lots of  
connections open at once - and it seems to cope extremely well.
