managed threads.

[Emperor]

hi,
 
I started developing my asynchronous connection manager. I think the
first implementation will use NBIO.
 
As I'm pretty new to avalon I don't really know how to implement a
manager. I don't really understand the blocks/services split up in the
cornerstone source. or is this deprecated? which interfaces should my
manager include?
 
I need some threads for the manager... how do I retrieve an instance? is
it the best way to implement multithreading?
 
thx,
 
Nils
