+The loading of the jax and extensions in steps 5 and 6 are now done in 
+parallel, rather than sequentially.  That is, all the jax and extensions 
+are requested simultaneously, so they load concurrently.  That means they 
+can load in any order, and that the begin and end signals for the jax and 
+extensions can be intermixed.  (In general, you will get `Begin Jax` 
+followed by `Begin Extensions`, but the order of `End Jax` and `End 
+Extensions` will depend on the file sbeing loaded.)  Both 5 and 6 must 
+complete, however, before 7 will be performed.
 
+See the ``test/sample-signals.html`` file to see the signals in action.
