1.13 + * of all the IRIX sprocs in a program when one of them dies due to an error.
1.14 + *
1.15 + * There are three sprocs in this test: the parent, the child, and the
1.16 + * grandchild. The parent and child sprocs never stop on their own.
1.17 + * The grandchild sproc gets a segmentation fault and dies. You should
1.18 + * You should use "ps" to see if the parent and child sprocs are killed
1.19 + * after the grandchild dies.
