 * Test sproc_ch.c
 *
 * 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.
