It is because there is no "setReference" method on an Alias.  As the  
comment says, if you want to delete, then recreate with a new  
reference, you need to make sure that the ACL and ownership information  
of the alias is properly transfered.  WRT to ACL, make sure you only  
transfer over the non-inherited ACL.

Though, I'll probably be adding a "setReference" function before to  
long (as part of the dash board).
