+        *   runnning httrack processes, to let browsers recover &
+        *   humans to get some urgent work done. (There were also
+        *   sometimes eg 2 httracks, 1 on each of 2 internal hosts,
+        *   both sucking different parts of the net, through 1 common
+        *   busy gateway, & although both rate limited, browsers still
+        *   timed out.
