This would be the parallel equivalent story for burgers. 🍔

For a more "real life" example of this, imagine a bank.

Up to recently, most of the banks had multiple cashiers 👨‍💼👨‍💼👨‍💼👨‍💼 and a big line 🕙🕙🕙🕙🕙🕙🕙🕙.

		// no action. Thus, we try an innocent seek to the current position
		// to see if Seek is really supported.
		pos1, err := sr.Seek(0, io.SeekCurrent)
		if pos1 >= 0 && err == nil {
			// Seek seems supported, so perform the real Seek.
			pos2, err := sr.Seek(n-1, io.SeekCurrent)
			if pos2 < 0 || err != nil {
				return err
			}
			seekSkipped = pos2 - pos1
		}
	}

	copySkipped, err := io.CopyN(io.Discard, r, n-seekSkipped)

Os próximos conceitos a serem considerados são todos sobre o programa que executa sua API real (por exemplo, Uvicorn).

## Programa e Processo

Falaremos muito sobre o "**processo**" em execução, então é útil ter clareza sobre o que ele significa e qual é a diferença com a palavra "**programa**".
