	proc isCounterLeaked*(name: string): bool {.noinit.} =
	## Returns ``true`` if leak is detected, number of `opened` not equal to
	## number of `closed` requests.
	let tracker = TrackerCounter(opened: 0'u64, closed: 0'u64)
	let res = getThreadDispatcher().counters.getOrDefault(name, tracker)
	res.opened == res.closed

it says Returns true if leak is detected, number of opened not equal to number of closed requests.
However it returns true if number of opened is equal to number of closed requests.
