be called at the end of each test that spawns children (perhaps it should be called from regrtest instead?). This will hopefully prevent some of the unexplained failures in the buildbots (hppa and alpha) during tests that spawn children. The problems were not reproducible. There were many zombies that remained at the end of several tests. In the worst case, this shouldn't cause any more problems, though it may not help either. Time will tell.
