That is a separate problem I think.  A user-space program should be
able to do anything [*] without causing the kernel to fall over.


[*] Well, if the program uses iopl() or messes with the x86 LDT I
suppose there could be a difference, but generally abitrarily-bad
bahaviour on the part of a user-space program should not result in the
kernel getting into difficulties.  This statement assumes that root
set up appropriate resource limits; if a program tries to allocate
130% of available virtual memory, the kernel is bound to have
difficulty delivering.
