Comment:

 @edsko: I think the code is correct ''as is''.

 `taskCount` is not decremented when a worker task is stopped, but only
 when `freeMyTask` is called, which frees the task bound to the current
 thread. So `taskCount` is the current number of bound tasks + the total
 number of worker tasks.

 I suggest to just add a comment to the definition of `taskCount`: `//
 currentBoundCount + workerCount`. Do you agree?
