 - open the gallery application with thousand of photos on the SD card (but not yet imported to gallery).
 - Do not scroll. Let the phone sit for > 1 hour while watching the gallery app.

 - Images continue to "pop" into the view while the phone is idle.

 - Without scrolling, images in the current view should not change.  As I understand it, only after scrolling down should one be able to observe more images loaded at the bottom.

Blocks: 858886
Photos are processed in whatever order the device storage scanning API returns them.  And then they are displayed newest first. So if DeviceStorage returns the oldest ones first, then new photos will always appear at the top of the list.

The workaround would be to scan all the photos first, put them in order, and then process them in a separate step in the chronological order.  I can do that, but it would mean slowing down scanning in the normal case in order to get better behavior in this fairly pathalogical test case.

(I don't believe that actual users of this phone are going to load 1000s of photos and scan them all at once.  In normal use, there will be a few new photos taken with the camera app, and the gallery will find them and display them at the top and be done.  So I'm really not too concerned about this.)

Why is this bug marked as blocking 858886?  That bug is fixed: the app no longer crashes.  But scanning now takes *forever*.  There's a gecko patch that I'm hoping will get uplifted that will allow us to make scanning faster again, though.
Oh, sorry. I see that 858886 is a new bug, not the old one that has been fixed.
