> In {{Storage.tryLock()}}, we call {{lockF.deleteOnExit()}} regardless of
> whether we successfully lock the directory. So, if another NN has the
> directory locked, then we'll fail to lock it the first time we start another
> NN. But our failed start attempt will still remove the other NN's lockfile,
> and a second attempt will erroneously start.
