Searching for a Utility for Dropping Semaphore with 1 Permit

Is there a a utility for a kind of "dropping semaphore" or "only allow one instance to run at once, discard all others"? The logic is simple but I wasn't sure if there was a builtin for it

   let isRunning = false
        const doStuff = () => {
            if (isRunning) return Effect.unit()
            isRunning = true
            return pipe(
                //......
                Effect.ensuring(Effect.sync(() => (isRunning = false))),
            )
        }

   let isRunning = false
        const doStuff = () => {
            if (isRunning) return Effect.unit()
            isRunning = true
            return pipe(
                //......
                Effect.ensuring(Effect.sync(() => (isRunning = false))),
            )
        }

   let isRunning = false
        const doStuff = () => {
            if (isRunning) return Effect.unit()
            isRunning = true
            return pipe(
                //......
                Effect.ensuring(Effect.sync(() => (isRunning = false))),
            )
        }
