Perl has traditionally had a concept of real and effective user-ids, 
which are accessible via the special variables $< and $>.  However, Perl 
has never had a concept of the third commonly seen privilege, the 'saved 

Paul will briefly explore the treacherous maze of unix privileges, how 
they can vary both between and within operating systems, and how often 
when you think you've dropped privileges, you haven't.  We will also

can be made to lie about the privileges it currently has available.

Finally, we will learn of a new way of manipulating privileges in Perl, 
and how this overcomes a number of existing problems.
