However it adheres privilege separation model (similar to OpenSSH), thus actually only a very small amount of code is running with root privileges. Moreover most of the crucial operations (job submission, stage-in/stage-out operations) are performed as target local user so even breaking the service would not give attacker any more privileges that he already has.
