Which is unfortunate as it means that any Product that defines its own
import step (be it via import_steps.xml or e.g. in the case of CacheFu
cache.xml) needs to stay in the Products directory forever.  If you
remove it (even after uninstalling it and restarting Zope and removing
it from Control_Panel/Products) the step is still in the registry.  So
it will give an error when you explicitly run it or when you run all
available steps, like this:

2007-07-31 19:43:34 ERROR Zope.SiteErrorLog http://localhost:8080/kantoor/portal_setup/manage_importSelectedSteps

I went in with a zopectl debug session a few weeks ago to remove such
a step manually from the registry.  That worked, but having a method
that you can call in an uninstall method that does this for you, would
be better.
