When I compile and run the following program:

#include <stdio.h>
int main(int x, char **y)
{
     pause();
}
... as:

./xxx `yes`

... the following occurs after about 30 seconds (your mileage
may vary):

This device, /dev/sdb1 is one of the mounted file-systems.
It is not being accessed. The root filesystem is on
an IDE drive (/proc/mounts):

rootfs / rootfs rw 0 0
/dev/root.old /initrd ext2 rw 0 0
/dev/root / ext3 rw 0 0
/proc /proc proc rw,nodiratime 0 0
/sys /sys sysfs rw 0 0
none /dev/pts devpts rw 0 0
none /dev/shm tmpfs rw 0 0
/dev/sdb1 /home/project ext2 rw 0 0
/dev/sda1 /dos/drive_C msdos rw,nodiratime,fmask=0022,dmask=0022 0 0
/dev/sda5 /dos/drive_D msdos rw,nodiratime,fmask=0022,dmask=0022 0 0
sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0

This continues until the system is too sick to even be re-booted
from the console. It requires the reset switch.

It looks like the command-line argument is probably overflowing
something in the kernel, resulting in non-related problems.

Cheers,
