* 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.
