Same for me: All python lists take hours to distribute the mails.

The tricky thing is: Deletion of keys behaves differently
on Win95/98 and NT/2000.
(Quoting MSDN:)
The RegDeleteKey function deletes a subkey.

Windows 95/98: The function also deletes all subkeys and values. To delete a
key only if the key has no subkeys or values, use the SHDeleteEmptyKey
function.

Windows NT/2000: The subkey to be deleted must not have subkeys. To delete a
key and all its subkeys, you need to recursively enumerate the subkeys and
delete them individually. To recursively delete keys, use the SHDeleteKey
function.
(end quote)

The SHDelete* funtions require version 4.71 of shlwapi.dll, which
is included in Win98 or 2000 (or in IE 4.0).

So you should simply ignore this. We will work it out on distutils.
