+      Kernel threads and interrupts all run in same address space,
+      using several different synchronisation mechanisms

+    <li>
+      Kernel's 'lockdep' system dynamically tracks locking operations
+      and detects <em>potential</em> deadlocks
+    </li>
+    <li>
+      Now available as a userland library!  Except we need to package
+      it (build from linux-tools source package)
