To be more specific about RTAI/Fusion, there are more important features
in RTAI/Fusion than the IRQ shield, namely : 
- the preservation of priorities upon threads migrations between the
  RTAI and Linux domains ;
- the ability to debug user-space realtime threads with unmodified
  versions of gdb ;
- proprietary RTOS emulators (available both in kernel-space and
  user-space), easing the migration from such RTOSes to RTAI.
