/socket.io/0.6.16/ must be 0.6.17

[tglines]

We thought this issue was closed and fixed but it seems that there may be more to it.

I noticed when updating from socket.io 0.6.16 -> 0.6.17 it cut down the frequency of occurrance drastically, yet it still did happen now and then.

I am experiencing this too especially when using xhr polling . I believe this is purely a socket.io issue though
