Shugo:

Thanks for the explanation. What does it mean when you say "objects  
created by untrusted code are tainted and untrusted?" I tried:

dave[RUBY3/Book 11:04:03*] irb
irb(main):001:0> class Dave;end
=> nil
irb(main):002:0> Dave.untrust
=> Dave
irb(main):003:0> d = Dave.new
=> #<Dave:0x108cf4>
irb(main):004:0> d.untrusted?
=> false
irb(main):005:0> d.tainted?
=> false


Is there an example of a sandbox that uses trust?
