+// stop(true) from alpnCallback or serverName closes the socket whose SSL call
+// is on the stack, so that close waits until the callback returns. stop(true)
+// once spun on that socket and never returned. The fixture runs in a child
+// process, because such a spin also blocks the event loop that times a test

+// test leaves behind only when that test runs alone.
