i asked clint(AT)debian thus

  If intercepted system calls try to chown() to the very user and
  group that fakeroot reported that a file has, and the stat cache
  gives a hot entry for the file thus, wouldn't it make sense to
  assume that "something like the above" is the desire of the
  programmer?
  "Faking" the operation in such a context does not appear overly
  grazy to me?  What do you think?
