…pping the runloop when done
Make readStream non-atomic

…alidated and it leaks the whole request
Stop reading request headers in handleBytesAvailable - they are now read only in handleStreamComplete.
This change prevents a neverending loop of ASIAuthenticationDialogs caused by the new lockless delegate authentication system.
(It also means the request body will always get downloaded, which may be useful sometimes when failing authentication)

…vents a crash for async requests when only the timer is retaining the request

Fix a potential leak when creating a request where the old stream would not get released if opening the new one failed
statusTimer is now a retained property
Tweak tests to remove leaks

Add helpful comments to some of the new additions, reinstate refs to the mailing list posts that were so helpful

…her than only when it's the same request
Test tweaks
