I've gone through and checked all the cases where we used to have warnings for
do-statements throwing away results, checking that it is ok to throw them away,
and using void in places where we had been doing '_ <- foo; return ()'

* Remove two do-notation warnings in Lock

cleanup. In the second, we don't care what exit code running the editor gave.
