Description of problem:


Version-Release number of selected component (if applicable):
katello-0.1.304-1.el6.noarch

How reproducible:


Steps to Reproduce:
1. See comment #6 in upstream bug (see "depends on") (copied here):

create a system w/ a fact of 64 cpu sockets and view that
system using a manifest w/ a product that covers less sockets. Toggling
checkbox will now show the lesser socket subscriptions where previously they
were not shown.
  
Actual results:
See comment #9 in upstream bug (copied here):
there is an unacceptable delay between the time you check
the checkbox, and when the list updates.  Nothing indicates to the user that
the app is busy. The "working" cursor appears for about 1/2 second, the normal
cursor returns, and then finally the list updates about 4 seconds later.  

That's enough time for a user to figure the content isn't there and navigate away.

Expected results:
"Working" cursor stays until list is updated.
