VMs from a pool are stateless (return to base on shutdown) if:
- started from admin portal as stateless (via runonce)
- started from user portal (as-is) in an automatic pool

VMs from a pool are statefull if:
- started from admin portal
- the pool is manual - until the VM is "returned to pool".

admin not being stateless allows to do the following;

- create the pool
- start the VMs from the admin portal (say, to have them sysprep)
- shut them down, take a snapshot!
- now use them as statless with the snapshot

(Omer - was this use case checked with template versions - that all 
snapshots are deleted? does it delete the entire VM?)
