Hmmmmm.  VERy interesting.  Considering this project is for a very sensitive 
customer, it looks like it's time to hack the source.  (Fortunately we have 
that option.)

On a more general note:  Many, many thanks to those that responded to my 
question.  I'm glad to learn that my concern was groundless.  (And I get to
learn a little more about the Unix kernel, which is always nice.)

Happy hacking, kernel-wise!
