[Zope] Start a new thread from a request

I've got a Zope application that accepts some data from a user and uses it in an XML-RPC call to another server. The XML-RPC can take some itme, so I would like to put it into another thread and immediately return a page to the user. I've heard something about how I need to provide my new thread with a connection to the ZODB, but have not found a recipe. Any help appreciated. Wade Leftwich Ithaca, NY
