Description of problem:

when you edit a disk to add bootable/shared/wipe or remove them, the changes take about 5 seconds. 
so if I reopen the disk it seems that the change has not been updated. 
since these are simple db updates they should take milliseconds and not 5 seconds (and I am working with a local db). 
also adding a regression on this since this behaviour did not happen in 3.0

Version-Release number of selected component (if applicable):

si14

How reproducible:

100%

Steps to Reproduce:
1. create a disk and attach it to a vm
2. edit -> add boot tag -> save -> edit (same for wipe and share)
3.
  
Actual results:

it takes the change 5 seconds to be updated 

Expected results:

since these are simple db updates they should not take that long
