XenAPI was not implemented to allow for multiple simultaneous XenAPI requests. A single XenAPIConnection (and thus XenAPISession) is used for all queries. XenAPISession's wait_for_task method would set a self.loop = for looping calls to _poll_task until task completion. Subsequent (parallel) calls to wait_for_task for another query would overwrite this. XenAPISession._poll_task was pulled into the XenAPISession.wait_for_task method to avoid having to store self.loop.
