Some test cases in Lib/test/ are problematic for users
wishing to test their own implementations of the mapping protocol: 

 - TestHashMappingProtocol.test_repr() requires the user implementations
to look like a dict when repr() is applied. It is unclear why this is
required of conforming mapping protocol implementations.
 - TestMappingProtocol.test_fromkeys() cannot pass for any
implementation that uses its constructor in fromkeys(), because baddict1
defines a constructor accepting no arguments. It should accept *args,
**kwargs to be sane for user implementations that handle passing data
sources to the constructor.
 - TestHashMappingProtocol.test_mutatingiteration(), for some faulty
implementations, makes the iteration degrade into an infinite loop.
Making the test more strict (eg. keeping an explicit iteration count and
failing if it goes >1) would be more helpful to buggy implementations.

These all seem like trivial issues. If it is agreed that the repr_test
should be removed from the ABC tests, I can provide a patch implementing
these three corrections.
