Investigate possible slowness in getFirstWorkingFamily/cy.visit()

Lines 161 to 169 in 943c578

	return getFirstWorkingFamily(options, this.familyCache, (family: net.family) => {
	options.family = family
	if (isHttps) {
	return this.httpsAgent.addRequest(req, options)
	}
	this.httpAgent.addRequest(req, options)
	})

This can add up to a second to the initial request to a domain, and we need to double-check that this is all network latency and there's nothing untoward going on here.

Is this actually happening? Got lost in the blur of other performance changes.
