Description:
Severe lag occurs when navigating the messages app when the user has 2000 SMS and MMS messages. It takes several seconds to open a SMS, edit messages or to exit a message thread.

Repro Steps:
1)  Updated Buri to Build ID: 20131126004001
2)  Ensure the test device has a mixture of 2000 SMS and MMS messages saved. Use the script ./makeReferenceWorkload.sh x-heavy if necessary.
3)  Tap the "Messages" icon.
4)  Wait for all the SMS and MMS messages to load on the device.
5)  Tap on a message to view the message thread.
6)  Tap on the "Back arrow" to go back to the main messages page.
7)  Tap on the "Check mark" in the upper right corner of the screen to edit the messages.
8)  Tap the "X" button to cancel the edit.

Actual:
It takes several seconds to navigate to anywhere in the messages app or to edit messages. Severe lag occurs.

Expected:
The user can navigate the messages app smoothly without any noticeable lag occurring.

We are working on getting the script to work on the Leo v 1.1.0 COM RIL. As soon as we have this working, I will update this issue further on whether or not it occurs on v 1.1.0.
