Summary: fcntl.lockf broken?

Initial Comment:
fcntl.lockf appears broken to me. It always gives me
"bad file descriptor", even though I can use the file
object from which it is derived:

>>> import fcntl
>>> f = open("names.db", "r")
>>> fcntl.lockf(f.fileno(), fcntl.LOCK_EX)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
IOError: [Errno 9] Bad file descriptor
>>> data = f.read()
>>> len(data)
45056

Since posixfile is officially deprecated, this would
be nice to have working...

Environment: Mandrake 8.1, gcc 2.96, glibc 2.2.4
