+# Dict resizing bug, found by Jack Jansen in 2.2 CVS development.
+# This version got an assert failure in debug build, infinite loop in
+# release build.  Unfortunately, provoking this kind of stuff requires
+# a mix of inserts and deletes hitting exactly the right hash codes in
+# exactly the right order, and I can't think of a randomized approach
+# that would be *likely* to hit a failing case in reasonable time.
