Closing this. I've added a comment to the source pointing to
here.

Hmm, strange. I should perhaps have provided the link that I
based this on: http://www.cygwin.com/faq/faq_3.html#SEC41. 
The thing is, the test needs a permissions error so it can
check shutil.rmtree's error handling. Setting the
permissions for the directory to stat.S_IREAD (0400) doesn't
seem to prevent Python from removing the file. I don't know
enough about the intricacies of Cygwin+chmod (I don't have a
Windows machine) to make this work reliably, but I'll be
happy to take another patch.

Note, by the way, that this is not a problem with shutil
itself, but just with the test.

I disagree, chmod seems to work:
[11:35] - adp96: touch zzz
[11:35] - adp96: ll zzz
-rw-rw-rw-    1 mikit    Domain U        0 Nov 23 11:35 zzz
[11:35] - adp96: python -c 'from os import chmod;
chmod("zzz", 0700)'
[11:36] - adp96: ll zzz
-rwx------    1 mikit    Domain U        0 Nov 23 11:35 zzz

Ah, seems like chmod doesn't work on Cygwin. That means
there's no way to run this test there, so I've changed it so
that it doesn't run on Cygwin anymore.
