Bug on Python2.3.4 [FreeBSD]?

Hi,

AFAICT there seems to be a bug on FreeBSD's Python 2.3.4 open function. The
documentation states:

> Modes 'r+', 'w+' and 'a+' open the file for updating (note that 'w+'
> truncates the file). Append 'b' to the mode to open the file in binary
> mode, on systems that differentiate between binary and text files (else it
> is ignored). If the file cannot be opened, IOError is raised.   

Consider:

$ cat test
lalala

$ python2.3
Python 2.3.4 (#2, Jan  4 2005, 04:42:43)
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.
>>> f = open('test', 'r+')
>>> f.read()
'lalala\n'
>>> f.write('testing')
>>> f.close()
>>>
[1]+  Stopped                 python2.3
$ cat test
lalala

-> write did not work; ok

$ fg
python2.3
>>> f = open('test', 'a+')
>>> f.read()
''

-> append mode does not read from file, *not ok*

>>> f = open('test', 'w+')
>>> f.read()
''
>>>
$ cat test

-> w+ truncated file, ok


Can anyone confirm that? Is there any other way of opening a file for
appending instead of a+? 

Thanks,
Ciao
