[Zope] Is this possible to daemonize a process launched from Zope ?

Hi, I'd want to know : has someone ever tried to launch a process from Zope and daemonize it so that it runs by itself and doesn't hang one zope thread ? I'm thinking about the fork+exec with controlling terminal and process group detachment, available under *nix systems. Is such a thing possible ? Are there any drawbacks ? (beside not being portable to Win) I know I could try and see by myself, but if someone has already done it or says its impossible, then I'd better know now. Thanks in advance Jerome Alet
