r18166 (sacarg rewrite) breaks snet-rts/lpel
Extended Description
r18166 breaks snet-rts, segfaulting in SACARGunwrapUdt(). Even when using only a single thread.
Sorry, no time to debug it further now, as I am leaving Advance on Friday, maybe I will have to temporarily revert the whole patch later because I _really_ need to bring all the pieces (sac, lpel, snet-rts) into *a* consistent state :-(
