Subject: File.chown removes setuid permission

Is this behaviour deliberate, or a bug? The chown binary from gnu coreutils
does not do this.

Example:

rubyx@atlas bb $ echo "test" > test
rubyx@atlas bb $ chmod +sx test
rubyx@atlas bb $ ls -l
total 4
-rwsr-sr-x    1 rubyx    users           5 Aug 29 19:56 test
rubyx@atlas bb $ sudo irb
irb(main):001:0> File.chown(0,0,'test')
=> 1
irb(main):002:0> exit
rubyx@atlas bb $ ls -l
total 4
-rwxr-xr-x    1 root     root            5 Aug 29 19:56 test
rubyx@atlas bb $
