The best way to release a Semaphore when Fork is involved

const postMessages = (worker: Worker | MessagePort) =>
  pipe(
    semaphore.take(1),
    Effect.zipRight(outbound.take),
    Effect.tap(([request, deferred]) =>
      Effect.sync(() => {
        const id = idCounter++
        requestMap.set(id, deferred)
        return worker.postMessage(
          [id, payload(request)],
          transferables(request),
        )
      }),
    ),
    Effect.tap(([, deferred]) =>
      pipe(
        Effect.ignore(Deferred.await(deferred)),
        Effect.zipRight(semaphore.release(1)),
        Effect.fork,
      ),
    ),
    Effect.catchAllCause(() => semaphore.release(1)),
    Effect.forever,
  )
