}The AIX 3 kernel is:
  
}o  Pageable (most of the kernel doesn't hog up real memory when not in use)
}o  Pre-emptable (device drivers and kernel routines can be interrupted by
}   higher priority tasks and interrupts, allowing a more responsive system)
}o  Has dynamically definable/deletable/reconfigurable device drivers
}o  Has dynamically definable/deletable kernel extensions (you can add
}   new system calls to the kernel as the system runs without a kernel rebuild)
}o  Improved realtime capabilities (due to the pre-emptable kernel etc)
 
    Hmmm, how novel...and how many years have these things been in VMS?
   
    Oh, sorry I forgot we're not supposed to use the V-word,
