Applied a number of idiomatic changes.

Uses of the 'sort()' method were converted into calls of 'sorted()' when
possible and the sorted() expression was inserted into a subsequent statement
whenever that made sense.

The statement 'while 1:' was changed to 'while True:'.

Names from the 'types' module (e.g., 'types.FooType') were converted to the
equivalent build-in type (e.g., 'foo').

Comparisons between types were changed to use 'isinstance()'.
