Chris Larson ada2a8494a Avoid unnecessary calls to keys() when iterating over dictionaries.
dict objects provide an __iter__ method for the iteration which gives you the
keys, so calling keys directly is unnecessary, and isn't really a best
practice.  The only time you really need to call the keys is if there's a
danger of the dict changing out from underneith you, either due to external
forces or due to modification of the iterable in the loop.  Iterations over
os.environ are apparently subject to such changes, so they must continue to
use keys().

As an aside, also switches a couple spots to using sorted() rather than
creating a temporary list with keys() and sorting that.
