> thread creation is quite expensive and so a new thread per unit of work is also expensive, i propose to use util.concurrent threadpools in the java binding sub-project and enhance unit tests e.g. with countdown latches to ensure competing test threads start simeltanously and semaphore to throttle access to running units of work.
> affects FreePool, TodoManager and associated tests and possibly more classes
