------------------------------+-----------------------------
 Due to implementation flaws, there may be an infinite recursion in the
 signal processing even if ASR mode is disabled during signal processing.
 The problem is that rtems_task_mode() is used to set up and tear down the
 ASR-specific task mode. This needs to be changed to set the modes under
 protection of the right locks and using a loop instead of recursion to
 schedule the next ASR processing step if needed.
