I'm running trinity as user, and using: MALLOC_CHECK_=0 ./trinity -xinit_module -xreboot -xshutdown -xunshare -xnfsservctl -xclock_nanosleep -xuselib -xumount -xmount -m --quiet -C 400 -l off -xmremap to run it. I'm currently also running with syscall and a few other trace bits enabled, but I suppose that shouldn't affect things too much. The machine is running Debian wheezy with a few choice testing bits.
