Re-add sleep of 2 sec before looking for partitions (#172)

This fixes issue #162 and #165. I refactored the timeout handling,
with #169 by increasing the existing timeout and removing the additional 2 sec
sleep, because the 2 sec sleep was not working in all cases.
Unfortunately, the increase alone is not sufficient, so I'm re-adding
the 2 sec sleep again.
