00041  * The purpose of this test and the sproc_p.c test is to test the shutdown
00042  * of all the IRIX sprocs in a program when one of them dies due to an error.
00043  *
00044  * There are three sprocs in this test: the parent, the child, and the 
00045  * grandchild.  The parent and child sprocs never stop on their own.
00046  * The grandchild sproc gets a segmentation fault and dies.  You should
00047  * You should use "ps" to see if the parent and child sprocs are killed
00048  * after the grandchild dies.
