+ * In-Kernel Block Memory Allocation
+ * =================================
  *
  * The kernel reserves some memory for internal operation, since  malloc 
  * is not available.
+ *
+ * Threads
+ * -------
+ * kballoc() and kbfree() are protected with spinlocks so you can 
+ * call them simultanously, even from multiple cpus! 
+ *
+ * Todo
+ * ----
+ * zeroalloc, alloc bytes, realloc
