Hi, I need to have some processing done in one thread, that will set some attributes of a (non persistent) object. This processing is completely independant from Zope objects. Zope objects (persistent or non-persistent) will only need to "read" data from this object. What would be the best way to do this (specially how to initialize my thread ?)
