No need to be alarmed. You probably compiled a kernel with verbose usermode 
fault debugging, which spits out this stuff on ever fault a usermode 
application makes. Just disable this option in the kernel debugging section 
and recompile the kernel. There's nothing wrong with your application, what 
you see is the result of the kernel paging in pages from backing storage as 
the program execution proceeds.
