Socket.IO does not intercept first client file request

[jed]

It looks like Socket.IO fails to intercept the first request for the client files when it is added as a listener after another app.

so assuming that

function app( req, res ) {
  res.writeHead( 200, {} );
  res.end( "done." );
}

this will serve successfully:

var server = require( "http" ).createServer( app )
  , socket = require( "socket.io" ).listen( server );

server.listen( 8000 );

but this will result in a 404 for the first request only, and serve successfully on subsequent requests:

var server = require( "http" ).createServer()
  , socket = require( "socket.io" ).listen( server );

server.listen( 8000 );

server.on( "request", app );

I'm not sure if this is entirely related, but I just had to do a patch on my socket.io fork to prevent it from setting the request to null in client._onClose so I could pass a request through the Connect app. This feels like a hack, but along with stopping the unsetting of this.request, I added removeAllEventListeners before AddEventListener to deal with memory issues on the now persistent request.
