Select a bunch of systems in SSM and delete them. What happens is they get queued for deletion but get actually deleted in an asynchronous process. Given that it takes about > 10 secs to delete a system if the user was deleting a 100 systems, it'd take around 1000 secs. At this stage some systems still be browsable through SDC even though they are technically "Deleted". We would need to change the SDC header to Hide the system and say "the following system has been deleted and you can't browse it"
