 *  New: Support `Expect: 100-continue` as a request header. Callers can use this header to
    pessimistically hold off on transmitting a request body until a server gives the go-ahead.
 *  New: Permit network interceptors to rewrite the host header for HTTP/2. This makes it possible
    to do domain fronting.
 *  New: charset support for `Credentials.basic()`.

	// This bound is also special because it applies to both the trigger
	// *and* the goal (all other trigger bounds must be based *on* the goal).
	//
	// It is computed ahead of time, at commit time. The theory is that,

	// will be chosen to always give the sweeper enough headroom. However,
