- *   By always taking all of the uspace IRQ hash table lock, IRQ structure lock

- *   either see the IRQ structure present in both the hash table and the
- *   answerbox list or absent in both. Views in which the IRQ structure would be
- *   linked in the hash table but not in the answerbox list, or vice versa, are
- *   not possible.
- *
- *   By always taking the hash table lock and the IRQ structure lock, we can
- *   rule out a scenario in which we would free up an IRQ structure, which is
- *   still referenced by, for example, an IRQ handler. The locking scheme forces
- *   us to lock the IRQ structure only after any progressing IRQs on that
- *   structure are finished. Because we hold the hash table lock, we prevent new
- *   IRQs from taking new references to the IRQ structure.

  * @brief   Udebug hooks and data structure management.
  *
  * Udebug is an interface that makes userspace debuggers possible.
+ *
+ * Functions in this file are executed directly in each thread, which
+ * may or may not be the subject of debugging. The udebug_stoppable_begin/end()
+ * functions are also executed in the clock interrupt handler. To avoid
+ * deadlock, functions in this file are protected from the interrupt
+ * by locking the recursive lock THREAD->udebug.int_lock (just an atomic
+ * variable). This prevents udebug_stoppable_begin/end() from being
+ * executed in the interrupt handler (they are skipped).
+ *
+ * Functions in udebug_ops.c and udebug_ipc.c execute in different threads,
+ * so they needn't be protected from the (preemptible) interrupt-initiated
+ * code.
