The program and NT.

It is (or should be, IMHO) standard procedure for applications that 
nothing a normal operator (non-administrative) can do should cause the 
application to abnormally end, and certainly not take the entire system 
with it.  It's kind of like the guideline for network programming: Make 
your program to follow the standards strictly but to accept other 
programs breaking the stanmdard grossly.  Any program which crashes on a 
user error shouldn't go into a production system, in this day and age.

Beyond that, no application running in normal user space should be able 
to cause the system or network as a whole to go down.  Obviously, every 
OS has holes, and the goal if to find those holes before a program of 
importance does.

Unfortunately, C makes it frightenly easy to not test for errors and 
allow them to just propegate through a system until something 
catastrophic happens.
