Subject: [PATCH] Improve timeout behavior. (#169)

Instead of putting one timeout of 2 sec at the beginning of the check for
the loop devices, use the already existing timeout implementation
inside the loop and just increase the maximum timeout to 60 sec.
This improves the overall behavior, because as soon as the loop
devices are detected, the loop will be exited, but it also increases
the maximum possible time to wait for the loop devices. This is helpful
when being used on slower systems.
