Three method inTKTWatchDog, revealed by Code Critics.

The pool variable was removed in the same commit as dog in other class (See #8)

I'm learning...
AFAIU, before a TKTWatchDog had a single pool of workers but now it has a set of pools of workers.
This would require rewriting TKTWatchDog>>hasPoolWorkerNamed: which is used from here:

TKTServiceManager
>>
poolWorkerNamed: aString
	<return: #TKTCommonQueueWorkerPool or: nil>
	^ self services 
		detect: [ :any | any hasPoolWorkerNamed: aString ]
		ifFound: [ :aService | aService pool ]
		ifNone: [ nil ]

(another Tasker extension)
