No it is not deprecated. The one in Excalibur is in scratchpad. I had
written it to support the CommandManager. The CommandManager is used to
handle Command events, and the package also defines an EventPipeline.
The EventPipeline mapps events from a Source to an EventHandler.
Each ThreadManager is designed to have a different ThreadPool policy.
For instance, you can have one finite sized ThreadPool for all
EventPipelines, or you can have a ThreadPool per Pipeline, etc.
Currently, there is only one policy implemented, but there is room
for more.
