+  We have some problems with pantasks and pcontrol that result in some
+  low throughput.  here are the symptoms of which I'm aware:
+
+  * pantasks stops removing entries from the books, despite having
+    DONE or error states.
+
+    * I don't know of any particular reason for this, but my best
+      guess is that the load tasks are quitting before finishing the
+      lookup.  l don't know when or why, but added measurement may
+      help.  
+
+  * pcontrol seems to get very slow and large.  are we failing to
+    clear out some jobs??
