#### 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.

From that individual connections will be spawned to each remote server,
or incoming requests will be hooked up to the appropriate connection.

To get a connection to a specific server, use `Manager.Connection(host)` to get a connection to the specified host.
From this connection individual requests can be made.

Each handler, with optional subroutes can be registered with the manager using

		t.Fatalf("Failed, got error: %v, rows affected: %v", result.Error, result.RowsAffected)
	}

	tx2.Commit()
	// Attempt to convert the connection pool of tx to the *gorm.PreparedStmtDB type.
	// If the conversion is successful, ok will be true and conn will be the converted object;
	// otherwise, ok will be false and conn will be nil.
	conn, ok := tx.ConnPool.(*gorm.PreparedStmtDB)
