/********************************************************************************************************************
 * Following enum is used to identify the cause of error in the middle process (M) to the main thread (P)
 * during the startup of a Job. (passed to the parent (P) through the exit status).
 * The last two enums are special. They MUST be the last two for any new additions in the future.
 * The last one identifies the end of the enum list. Last but one (joberr_tryagain) is used to identify
 * the situations where trying again by the main thread might succeed (like errors due to insufficient
 * swap space etc..). When the middle process comes across an error that it thinks is worth trying again,
 * it adds joberr_tryagain to the main status (one of the status' upto joberr_tryagain) and exits with the new status.
