 forget to leave a critical section (which, in general, will lead to serious
 and difficult to debug problems).
 

+Example of using it:
+
+\begin{verbatim}
+void Set Foo()
+{
+    // gs_critSect is some (global) critical section guarding access to the
+    // object "foo"
+    wxCriticalSectionLocker locker(gs_critSect);
+
+    if ( ... )
+    {
+        // do something
+        ...
+
+        return;
+    }
+
+    // do something else
+    ...
+
+    return;
+}
+\end{verbatim}
+
+Without wxCriticalSectionLocker, you would need to remember to manually leave
+the critical section before each {\tt return}.
