The waf test that asks a question while every outside source hangs now
runs it in a synctest bubble and checks that the answer comes after
exactly the GeoJS wait, within the time limit. GeoJS is the silent
stand-in; the lists are fetched outside the bubble. A resolver stand-in
holds the DNS blocklist's query until the checks are done, so a waf that
waited for the query would answer only after it failed, which the test
catches.
The routewatch test for a hanging routewatch runs Route in a synctest
bubble, against a stand-in on Go's default transport, and requires
no_answer_yet after exactly zero time.
