It acquires 'getUsers' from somewhere, I guess.

Group objects have 'getGroupMemberIds' and 'getGroupMembers' methods.
You can see this in Products.GroupUserFolder.GroupDataTool.GroupData.
the Products.GroupUserFolder.interfaces.portal_groupdata is a bit
cleaner, but seems a little behind the times, as it's missing
'getGroupMemberIds'.

Note that this isn't a good topic for zope-dev, but more for plone-users.
