This change decreases the time when importing a module which is already in sys.modules. If you will run the following script:

import time
start = time.time()
import io
mid = time.time()
import io
end = time.time()
print(mid - start)
print(end - mid)

Before the change you will get:

0.0029745101928710938
0.00000667572021484375

After the change:

0.002993345260620117
0.000006198883056640625

This looks good to me, tiny speed enhancement, but also a code simplification.
