+Easy:
+ * Add a mechanism to recover from situations where the scheduler fails to send its reply message.
+  * Add a reply_pending field to host table.  Set at start of scheduler, clear after reply message sent.
+  * If get a request from host with reply_pending==1, scan for lost results
+ This would replace the <resend_lost_results> mechanism.
+
 Medium:
  * When using HR, if the scheduler has sent one result of a WU using a particular app version, it should use the same app version for other results from that WU.  Otherwise, when new app versions are released, results may incorrectly be marked as invalid.
+
 Hard:
  * Implement a mechanism so that server software detects incompatible database format.
- * Scheduler: implement mechanisms so that servera ttempts to send results from the same WU to hosts with similar turnaround time, so that a fast host doesn't have to wait weeks to get credit. 
+ * Scheduler: implement mechanisms so that server atempts to send results from the same WU to hosts with similar turnaround time, so that a fast host doesn't have to wait weeks to get credit. 
  * Implement a "reference WU" mechanism.
   * Add "reference WU ID" field to app table. Every host must complete the reference WU before it is sent any other jobs for that app.
