Title: Fix bug where dummy_thread was always imported

The code always import the dummy_thread module even on platforms where the real thread module is available. This caused bugs in other packages that use this import style:

try:
from _thread import interrupt_main # Py 3
except ImportError:
from thread import interrupt_main # Py 2
