INTERNAL_ERROR_THREAD_EXITTED, but what thread ?

[Matthew J Fletcher]

Hi,

It looks like the context has already changed by the time the
thread_exitted extension is called, so RTEMS_SELF does not get what you
want.

The rtems_tcb structure however contains 'Object->id' and 'Object->name'
which show the previous task running.
