[Zope] Reimporting products without restarting server

Having a slow machine, not having to restart the server when testing is important for me (it is a 20 second start up for me). Is there a script around to let me do this... ? Here is what I have done so far (using bits of snippet from the source): log into the monitor, and do this: import Zope app = Zope.app c=app() OFS.Application.initialize(c) c._p_jar.close() del c The net result is all items in the the "Add New Item" combobox double up, and I am not even sure if this does the trick...
