 if the keys and values don't support comparisons other than ==.

+ - Comparing dictionaries in ways other than == and != is slower: there were
+ insecurities in the dict comparison implementation that could cause Python
+ to crash if the element comparison routines for the dict keys and/or
+ values mutated the dicts. Making the code bulletproof slowed it down.
