| * The purpose of this test and the sproc_p.c test is to test the shutdown |
| * of all the IRIX sprocs in a program when one of them dies due to an error. |
| * |
| * There are three sprocs in this test: the parent, the child, and the |
| * grandchild. The parent and child sprocs never stop on their own. |
| * The grandchild sproc gets a segmentation fault and dies. You should |
| * You should use "ps" to see if the parent and child sprocs are killed |
| * after the grandchild dies. |
