That depends on how much space is available on the volume/disks that are 
storing this file, and how many other domUs are running there.  If there are 
many other domUs, or if this comes close to filling up your entire physical 
disk/array, this may not be a good idea, because you may overallocate your disk 
space and end up filling up the disk.
