+;;;; FIXME: This test also occasionally hangs on Linux/x86-64 at least. The

+;;;; signal_interrupt_thread, but both (apparently) getting EAGAIN repeatedly.
+;;;; Exactly how or why this is happening remains under investigation -- but
+;;;; it seems plausible that the fast timers simply fill up the interrupt
