   ShadowSizeEstimate is now a static value.  If it's set to 0, we basically ignore it and do no swap space checking before starting up shadows.  If it's not set in the config file at all, it defaults to DEFAULT_SHADOW_SIZE.  Once it's set, we never try to recompute it.    Also, whenever we exec, we only exit with JOB_NO_MEM if errno was ENOMEM, otherwise we exit with JOB_EXEC_FAILED.  This way, SwapSpaceExhausted only gets set to TRUE if it should, not if we can't find the shadow binary or something.
