Cleaning up OOo Multi Threading

More or less frequently people complain about OOo in respect to multi threading. Either because it is complicated to implement a service, or that there is only few documentation, or that the UNO API is not thread safe, or that it does not scale etc.

Goal

The OOo Threading Effort attempts to clean-up OOos threading model (how to use threads) and to implement a Basic Threading architecture (where and when to use threads), providing an overview and documentation of the threads used in OOo. Further improvement is planned to be implemented in another effort, eventually leading to an Advanced Threading architecture.

Time Frame

Current understanding of the topic lets us think, that the changes of OOo on behalf of the threading clean up effort are going to be integrated into some of the next updates and will probably mostly be finished until mid 2006.

Efforts&Tasks

The below list of efforts and tasks shows what needs to be done.
