6async function operation1() {
7  steps.push('operation1.1');
8  await semaphore.acquire();
9  steps.push('operation1.2');
10  await semaphore.release();
11}
12
13async function operation2() {
14  steps.push('operation2.1');
15  await semaphore.acquire();
16  steps.push('operation2.2');
17  await semaphore.release();
18}
