この場合、例えばコマンドラインオプションの `--workers` で、コンテナ内に複数のワーカーを持つことは**避けたい**でしょう。**コンテナごとにUvicornのプロセスは1つだけ**にしたいでしょう（おそらく複数のコンテナが必要でしょう）。

（複数のワーカーの場合のように）コンテナ内に別のプロセスマネージャーを持つことは、クラスターシステムですでに対処しているであろう**不要な複雑さ**を追加するだけです。

### 複数プロセスのコンテナと特殊なケース { #containers-with-multiple-processes-and-special-cases }

もちろん、**特殊なケース**として、**コンテナ**内で複数の**Uvicornワーカープロセス**を起動させたい場合があります。

そのような場合、`--workers` コマンドラインオプションを使って、実行したいワーカー数を設定できます：

#### Per-Connection Locks

Each connection has its own lock. The connections in the pool are all in a `ConcurrentLinkedQueue`. Due to data races, iterators of this queue may return removed connections. Callers must check the connection's `noNewExchanges` property before using connections from the pool.

The connection lock is never held while doing I/O (even closing a socket) to prevent contention.

   * Call the {@code setCount()} method under test, but do not check its return value. Callers
   * should use this method over {@link #setCountCheckReturnValue(Object, int)} when they expect
   * {@code setCount()} to throw an exception, as checking the return value could produce an
