I suggest adding "sync &" after killall5 -15.
The idea is to initiate cache writeout earlier.
While your processes exit, and you wait for them to disappear,
storage will be already busily writing out all dirty blocks.
If umount hangs (it shouldn't... modulo bugs), having early
sync also would help to have more data saved by this point.
