When the buffer isn't filled to capacity a new slice is created that's smaller than the original. In that case the smaller slice is returned to the pool which prevents the rest of the capacity from being used again. The solution is to pass the original slice through and attach the length. This allows the original slice to be returned to the pool once the operation is complete. This change also simplifies the `sendChunk` method, ensuring that the buffer is returned to the TransferManager even when no bytes were read from the reader.
