Well, except that in this case the docstring for manage_changeProperties
is badly wrong, if you pass a mapping as first argument, it will think
it's a request and render a page you'll never use as a result, which
slows it down a lot.
The proper way to call manage_changeProperties is:
manage_changeProperties(foo=6, bar='blah')
or
manage_changeProperties(**somemapping)
I've been meaning to fix Zope for years but...
