2654 * s-taskin.ads: Minor comment fix.
2655 * s-tassta.adb (Abort_Dependents): Don't abort all dependents;
2656 just direct dependents. If this is actually an abort, each task

2659 time from Vulnerable_Complete_Master "for convenience" (i.e. to
2660 kill off tasks waiting at terminate alternatives), aborting
2661 indirect dependents is wrong, because it causes some unrelated
2662 tasks to get aborted.
