Doesn't this result in unlimited amount of connections?
I believe that the p.created < p.max guard should ensure we only get the specified max connections.

I believe (and correct me if I'm wrong) that makeOne should be safe to do. It spins up a goroutine that:
- Calls inc()
- inc() will check
p.created >= p.maxand if true, return false
- inc() will check
- If inc() returns false nothing happens
So makeOne should not create a new connection unless p.created < p.max. The benefit to letting makeOne do the logic is that it handles the concurrency better -- it locks the mutex appropriately.

Just checked, you are right.

Makes a lot of sense, since it is duplicated.
