…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
