"%GOBIN%\go" clean...

Ese "esperar otra cosa" normalmente se refiere a las operaciones de <abbr title="Input and Output – Entrada y salida">I/O</abbr> que son relativamente "lentas" (comparadas con la velocidad del procesador y la memoria RAM), como esperar:

* que los datos del cliente se envíen a través de la red
* que los datos enviados por tu programa sean recibidos por el cliente a través de la red

func setPutObjHeaders(w http.ResponseWriter, objInfo ObjectInfo, del bool, h http.Header) {
	// We must not use the http.Header().Set method here because some (broken)
	// clients expect the ETag header key to be literally "ETag" - not "Etag" (case-sensitive).
	// Therefore, we have to set the ETag directly as map entry.
	if objInfo.ETag != "" && !del {
		w.Header()[xhttp.ETag] = []string{`"` + objInfo.ETag + `"`}
	}

Pero en algún momento, no había otra opción que crear algo que proporcionara todas estas funcionalidades, tomando las mejores ideas de herramientas anteriores y combinándolas de la mejor manera posible, usando funcionalidades del lenguaje que ni siquiera estaban disponibles antes (anotaciones de tipos de Python 3.6+).

   * permits? As explained above, there is no unique answer. If we are primarily interested to deal
   * with underutilization, then we want stored permits to be given out /faster/ than fresh ones,
   * because underutilization = free resources for the taking. If we are primarily interested to
   * deal with overflow, then stored permits could be given out /slower/ than fresh ones. Thus, we
