When I delete all events via unifinder, Sunbird takes up to 100% of CPU

Reproducible: Always

Steps to Reproduce:
1. create new profile
2. import events (more, thatn 50-70 items)
3. select all fron unifinder and delete using del on keyboard -> CPU went to 95% for 5-10 seconds, no response, no refresh, but the result was ok, items have been deleted

Actual Results:  
events was removed

Expected Results:  
Sunbird should refresh and do not take all CPU

version: trunk, today

I have just realize, that problem is not with deleting but selecting, take a look:

- open Sunbird and any taks manager (eg windows task manager), that can present CPU, switch to "always on top"
- select item in unifinder
- press SHIFT and move cross up/down to select another one -> look at CPU, Sunbird takes for few seconds 80% of CPU
 and for this time, Sunbird does not respone

You can also use mouse for multiselection
so, this is problem, I think...

Ok, after changes in bug 314291 sunbird works much better and deleting is really fast
