You do not need a modified kernel for any of that. My first guess would be that your app runs out of memory, and the disk activity that you see is virtual memory in action. Run the test in single-user mode, disable swap and see what happens. Check that none of /etc/rc.d/init.d/... daemons are running (stop whatever you don't like). To push things to the limit, you can create a runlevel where your app is the only one started by init. That would be a decent setup for an embedded system. Also you can run your app -as init- (meaning that the kernel will start it as soon as it finishes booting.)
