+Bug-Description:
+
+With certain values for PS1, especially those that wrap onto three or more
+lines, readline will miscalculate the number of invisible characters,
+leading to crashes and core dumps.

+Bug-Description:
+
+In circumstances involving long-running scripts that create and reap many
+processes, it is possible for the hash table bash uses to store exit
+statuses from asynchronous processes to develop loops. This patch fixes
+the loop causes and adds code to detect any future loops.
