Uno/Effort/Binary/Extend Threading-Model
The Advanced UNO Threading Framework Effort
Status: in progress
changed: --Kr 12:37, 1 March 2006 (CET)
The UNO Threading Framework basically introduces the notion of an apartment into the UNO world. An apartment in UNO terms is a purpose environment. An environment can be seen as a dedicated part of a process, giving space for objects of the same ABI and the same purpose. An environment can only be entered and left via defined doors, being proxy objects representing objects outside respectively inside the apartment.
Purpose environments may be dedicated to MutExes or threads. In the sense, that a MutEx becomes acquired or a thread gets switched before a call enters an environment.
The following specifications and features give an overview over the UNO Threading Framework. The specifications roughly depend on each other in the order listed. For example, the Threading Models specification depends on the Implementation Environments, all pieces basically creating a stack.

Current understanding of the topic lets us think, that the changes of OOo / UNO on behalf of the Threading Framework are going to be integrated into one of the next updates, probably early in 2006.
