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
   (no kernel rebuilds)
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)
o  Etc.

Opinions are my own.
