Speaking of which, has anyone ever tried the following:
#include <signal.h>
main () {
register i;
for (i = 1000000; i; i /= 10)
while (sbrk (i) != -1)
;
kill (0,SIGTSTP);
}
% a.out<CR>
[1] + Stopped a.out
% a.out<CR>
[2] + Stopped a.out
% a.out<CR>
[3] + Stopped a.out
% a.out<CR>
...
After about six of them our paging area completely fills up and no
one can run anything. (Fortunately "kill" is built into the csh.)
You get a message like:
/usr/ucb/mail: Not enough core.
