Sorry of the terrible mistake
VM thread does malloc and free.
while (1)
{
if (do_malloc)
{
dbg (stdout, "allocating %lli bytes ...\n", bytes);
if (!(ptr = (char *) malloc (bytes * sizeof (char))))
{
err (stderr, "hogvm malloc failed: %s\n", strerror (errno));
return 1;
}
if (keep)
do_malloc = 0;
}
dbg (stdout, "touching bytes in strides of %lli bytes ...\n", stride);
for (i = 0; i < bytes; i += stride)
ptr[i] = 'Z'; /* Ensure that COW happens. */
if (hang == 0)
{
dbg (stdout, "sleeping forever with allocated memory\n");
while (1)
sleep (1024);
}
else if (hang > 0)
{
dbg (stdout, "sleeping for %llis with allocated memory\n", hang);
sleep (hang);
}
if (do_malloc)
{
free (ptr);
dbg (stdout, "freed %lli bytes\n", bytes);
}
}
