sorry to contradict you here, but the following C program
----------
#include<stdio.h>
main()
{
        FILE *f;
        f=fopen("/tmp/full","w");
        for(;;) fprintf(f,"hh");
}
-----------------
 
when ran with a 
bpsh 0 ./a.out          

just fills the ramdisk until bpsh 0 df gives 0% free...then nothing more happens,
the node 0 does not swap !

memory explodes as well.
I guess the program is writing to /dev/null, not reading from it.
