AfterFunc with go

[learnergo]

if smallestDuration > 0 {
		table.cleanupTimer = time.AfterFunc(smallestDuration, func() {
			go table.expirationCheck()
		})
}

AfterFunc creates a new goroute.Is it necessary to use 'go' in 'AfterFunc'

I think it's preferred because otherwise cleaning up the table (which can be a costly routine) would block the caller.

I think "go" should be here:

if item.lifeSpan > 0 && (expDur == 0 || item.lifeSpan < expDur) {
		go table.expirationCheck()
}

I think "go" should be here:

if item.lifeSpan > 0 && (expDur == 0 || item.lifeSpan < expDur) {
		go table.expirationCheck()
}

it will run more times, not just run once for smallestDuration
