Checks any current http connection.
Called from the Channel Poller's thread - will invoke
disconnect on the HttpUrlConnection is the poll has
exceeded 5 minutes. This'll cause an exception to
be thrown in the polling thread, within the poll method.
It'd be preferable to use the timeout setting feature
within HttpUrlConnection, but this is only a parameter
in the 1.4 release of the JRE.
