Summary: os.access reports true for read-only directories

Initial Comment:
It appears that os.access incorrectly reports write 
access to directories on network drives.  For example, if 
I have a read-only directory called foo\bar on a machine 
called homeserver, the following code always returns 
true:

print os.access("\\homeserver\foo\bar", os.W_OK)
True

Similarly, if I map above directory to a drive, the results 
are the same, i.e.:

print os.access("H:\bar", os.W_OK)
True

However, if I try to create a file in that directory, I get 
a permission error:

f = file("h:\foo\bar\test.txt", 'w+b')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
IOError: [Errno 13] Permission 
denied: 'h:\foo\bar\test.txt'

The tracker was set to auto-assign Windows reports to you, 
Thomas.  I disabled that (and Windows reports will be 
assigned to None by default now).

Please don't assign windows bugs to me.  Thanks.
