Revert r73401 per Raymond Hettinger's request.
...
The rational is the change might cause imcompatiblity problems with
PyYAML. In addition, Raymond wants to kept the different versions of
collections synchronized across Python versions.

Improve implementation with better underlying data structure
...
for O(1) deletions. Big-Oh performance now the same as regular
dictionaries. Uses a doubly-linked list instead of a list/seq
to track insertion order.
