For some value of "work".  The problem is that POSIX, and some systems
that are moving towards conformance with it, have a different idea of
how setuid(geteuid()) should work than the one that used to be widespread.
News wants to see that call set both effective and real uids.  The new
and improved definition doesn't do that.

This stuff is slated for revision.
