> JDK 1.6 has File APIs like File.getFreeSpace() which should be used instead
> of spawning a command process for getting the various disk/partition related
> attributes. This would avoid spikes in memory consumption by tasks when
> things like LocalDirAllocator is used for creating paths on the filesystem.
