What about a configuration option on the volume for delete type? I can see some
possible options:
* None - Don't clear on delete. Its junk data for testing and I don't want to
wait.
* Zero - Return zero's from subsequent reads either by zeroing on delete, or by
faking zero reads initially.
* Random - Write random to disk.
* Multipass - Clear out the space in the most secure mode configured. Multiple
passes and such.
Interesting idea, but for the "None" case I'd include the possibility
that the user will be encrypting their data.
Also, I don't see any point for random or multipass given that anyone
that really cares about it isn't going to trust their unencrypted data
to someone else anyways.
Lastly, the "zero on delete" case could conceivably end up costing more
since the provider could continue to bill for the volume while it is
being deleted.
