Can you explain why it's non-trivial, because it seems dead simple to me.
The euid applies to the entire process, but so do many other things, such
as current directory or the file-descriptor limit.
Of course, if you assume that euid only applies to the current thread, then
yes, that's fiendishly difficult to do. But the problem there is that the
assumption is faulty, not that setuid() or seteuid() are intrinsically
difficult to perform.
