#### 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.

/// tip | Dica

Se você levantar qualquer exceção no código da *função de operação de rota*, ela será passada para as dependências com `yield`, incluindo `HTTPException`. Na maioria dos casos, você vai querer relançar essa mesma exceção ou uma nova a partir da dependência com `yield` para garantir que ela seja tratada adequadamente.
