+This is copied from ../system.
+
+This test suite uses a virtual time, gettimeofday(), select(),
+poll(), kevent() and epoll_wait() Unix system calls are redirected:
+gettimeofday() returns a date in virtual/exponentially inflated
+delay from an epoch, select(), poll(), kevent() and epoll_wait()
+timeouts are deflated down to at least 10ms.
+
+These tests depends on LD_PRELOAD being supported by the runtime
+loader.
+
+Beware BIND clock uses unsigned integer, in 22 seconds isc_time_now()
+overflows and breaks assertions. Note 22 real seconds is 136 virtual
+years...
