I have some python scripts I want to use in Zope. Some of them are blocking, so I was thinking about creating some threads into Zope to use my python scripts. The "ExtProc" product may help you.

Does somebody knows if it is possible and how? From what you say in another message, your type of blocking seems not to be cured with a separate thread.

When executing your method via Xron blocks your Zope system, it will do so even, when executed in its own thread. You need a separate process. Dieter
