I am not an expert on rtems internals but it seem like to me one way for 
a task to set itself delete protected would be using rtems_task_mode() 
and define a new mode RTEMS_NO_DELETE. This could be used internally in 
rtems to fail any call to rtems_task_delete() if set. However, the thing 
about the deleting task blocking on rtems_task_delete() sound a lot more 
complex.

I looked in the cpukit/score/src area and see lots of thread*.c files. 
Is this approximately where you think this feature could be added?
