+Subject: Answer to problems running assignment 5
+
+Some people have been having problems running assignment 5.
+Unfortunately, the way the network gets initialized, if things
+don't get done in exactly the right order, you can get an error
+in sending the first packet to the socket.
+
+I have modified synch.h and synch.cc in code/, and re-compiled
+the contents of code/network.  I was then able to run the
+test case successfully, at least one out of two times.  See below.
+So, be careful out there!
