Comment (by Chris Johns):

 I took a closer look at the debug server code and saw a simpler solution.
 I have have added a new call:
 {{{
 /**
  * Suspend all running threads including the caller if not
  * excluded. Returns when the debugger has connected and continued.
  *
  * If wait is true and there is no remote connected wait then break.
  */
 extern int rtems_debugger_break(bool wait);
 }}}
 I think this is simpler and cleaner to implement and use and it also lets
 users make the call anytime to break the target.
