/**

   Retrieve a job-ID that can be used to refer to the job after the client's process has recycled. Currently, this will be the only way to retrieve a job handle (a distren_job_t) and, consequently, the only way to retrieve a finished render.

   A job ID is representable using a character string. Hopefully, they will be kept at a reasonably small length. It should be made up of alphanumeric characters so as to be useful in most situations. 

   @param jobid This will be set to a string allocated by the specified malloc implementation

   @param job The distren_job_t from which to retrieve a jobid
