 * Helgrind:
   - Helgrind GDB server monitor command 'info locks' giving
     the list of locks, their location, and their status.
+  - Race condition error message with allocated blocks also show

   - Helgrind now understands the Ada task termination rules
     and creates a 'H-B relationship' between a terminated task and
     its master. This avoids some false positive and avoids big
