void AsyncJob::Start ( const Pointer &  job)

Promises to start the configured job (eventually). The job is deemed to be running asynchronously beyond this point, so the caller should only access the job object via AsyncCalls rather than directly.

swanSong() is only called for jobs for which this method has returned successfully (i.e. without throwing).
