When the iscsi target is pointed at an existing data file to serve via
iscsi, it seems as though it rewrites all data in the file.  This has
been experienced on snv_69.

For instance...

zfs snapshot pool/[EMAIL PROTECTED]
zfs clone pool/[EMAIL PROTECTED] pool/ldom1-now
iscsitadm create -b /pool/ldom1-now/root ldom1-now

Notice that the disks in the zpool get hot and pool1/ldom1-now grows
to roughly the size of the /pool/ldom1/root.

It seems as though it is not destructive to the data, but the rewrite
is annoying because:

- The LUN won't come online until the rewrite is complete
- I lose the sparseness of the clone

Is there some reason that this is desirable?  Is there a way to disable it?
