Hmm, Neil made a good point in IRC that since you'd clearly have to require
real UID=0 (instead of just effective UID = 0 ie SUID) to enable this
(otherwise we're right back where we started), artsd wouldn't know what
user to drop permissions to anymore. So it won't work.
./configure --trusted-users (or the like) it is, to make an unsafe build if
desired for development purposes.
