Small comment on the patch:

                 def clear(self):
-                    for key in self.data.keys():
+                    for key in self.keys():
                         unsetenv(key)
-                        del self.data[key]
+                        del self[key]

It looks like the patched version will unsetenv twice, Change

del self[key]

to

dict.__delitem__(self, key)
