assuming you've got more stuff on disk than you have memory, that should
work, most of the time.

pretty much. something like:

#include <stdlib.h>

int
main () 
{
	size_t sz = 10 * 1024 * 1024;

	while (1) {
	    if (malloc (sz) == 0) {
	        break;
	    }
        }
	return 0;
}		


should do it. depending on how much memory you have, it can take a while
(several seconds).
