Dear Brian,

The function not implemented is "utime", is this a known bug ?

# cat test.py
import os,time
f = 'foobar'
a = file(f, "w")
a.write("a")
a.close()
os.utime(f, (long(time.time()), long(time.time())))

# python test.py
Traceback (most recent call last):
  File "test.py", line 7, in ?
    os.utime(f, (long(time.time()), long(time.time())))
OSError: [Errno 38] Function not implemented: 'foobar'
