+# GDB must always report the process's exit status based on the exit
+# status of the thread group leader thread.  Test that when multiple
+# threads exit simultaneously, GDB doesn't confuse the non-leader
+# threads' exit status for the process's exit status.  GDB used to
+# have a race condition that led to randomly handling this
+# incorrectly.
+#
+# Since the improper behavior is racy in nature, this test is not
+# expected to be able to reproduce the error reliably.  Multiple
+# executions (or increasing the number of iterations) might be
+# required to reproduce the error with a misbehaving GDB.
