os.nice (or docs) BUG?

[Roman Suzi]

The following from the Python docs:

   nice (increment)
          Add increment to the process's ``niceness''. Return the new
          niceness. Availability: Unix.

Contradicts what I see in python 1.5.2 - 2.1:

>>> import os
>>> os.nice(1)
0
>>> os.nice(5)
0

(and the process niceness become 6 as reported by top)

It's docs inaccuracy or os.nice() bug? Or glibc bug?

Which category to report it in the Bug tracker?

Sincerely yours, Roman Suzi
