of Toaster web server to track and capture multiple command-line
builds.

Also, provided better wording surrounding shutting down Toaster.

             The following commands show how to start a Toaster environment
             without starting its web server, perform BitBake operations,
             and then shut down the Toaster environment.
-            Once the environment is shut down, you can examine the
-            BitBake build statistics:
+            Once the build is complete, you can close the Toaster environment.
+            Before closing the environment, however, you should allow a few
+            minutes to ensure the complete transfer of its BitBake build
+            statistics to the Toaster database.
+            If you have a separate Toaster web server instance running, you
+            can watch this command-line build’s progress and examine the
+            results as soon as they are posted:
