Connection sharing child-to-parent promotion sometimes does not occur

[iominh]

Sometimes when connection sharing is enabled a child connection will not get promoted to become a new parent even if it's the only connection open.

For example, here is a scenario using the chat example:

Open chat window #1 -- it connects as long-polling, which is great
Open chat window #2 -- it connects as a local connection, which is great
Open chat window #3 -- it connects as a local connection, which is great
Close chat window #1. Chat window #2 or #3 connects as long-polling. This is fantastic :)
Close the chat window with the new long polling connection. Now, the last remaining local window does not promote itself to be the parent, so it cannot receive or send messages until it connects...

Does the fix for #602 which includes the statement check for IE 8 mean shared connections are not possible with IE 8? If so are there any workarounds for this? I am currently designing a site that is required to support IE 8.
