Threading application block?

Sorry if this question has been asked before, but is there any intention to
write a threading/process management application block (or did I miss
something and it already exists)? A common pattern for me when writing
software is to create a thread mananger and to create classes to manage
queues of work items that UI components can add requests to. We then use a
listener pattern to enable the thread to communicate results with interested
components.

Thanks,


Robin
