    * Scope: We use global scope since the operation is to be 
             completed even if the page closes.
    * Builder explanation: launch builder is used since it is a 
             fire and forget task the calling page doesn't care about     
             it's result. 
    * suspension: No this won't block the main thread but simply 
             start 'C'.
    *
    * We return the representative job.
