New 2.9.7 - NS - Displaying MMS causes "lag spikes"

[weedy]

While great strides have been made to render and query SMS faster these changes seem to have not been applied to the MMS code paths.

Scrolling through long or short SMS conversations is fairly quick now but I will get a 1-2 second pause when I have to load a MMS (either by scrolling to it or it is one of the last messages received).
This is not that bad on it's own, but coupled with the MMS restore bug suddenly the MMS app is pegging the cpu for minutes at a time to load each MMS in a thread and causing ANRs.

What ever the MMS app is doing to query the DB and process the resulting MMS data sucks.

Still present in 2.9.21. And getting worse as my MMS count increases.

While the spikes are still present in 2.9.29 they have been greatly reduced.
Tentatively want to call this fixed.
