Timeouts and freezes handling 70Gb photos.

[viulian]

I'm have about 70Gb of photos on my sdcard ... MediaStore API never shows some of the albums, and thus, "MediaRetriever" is enabled in the Settings.

1. If Camera Roll is just started, it stays black instead of showing the cached thumbnails for all albums. Eventuall a small message "timeout" is seen, followed by "Loading failed RETRY"; I press Retry, eventually the albums are rendered. However, it should show a cached version of the list of albums while it scans in the background and updates the list of the fly ?

2. If I enter a big folder, CR starts "thumbnailing". I quickly try to scroll to the bottom of it since I look for something old for example. Scrolling is slower and slower, phone gets hot and eventually everything becomes sluggish. I decide to press Back. Instead of going back and cancelling the "thumbnailing", CR decides it wants to scroll to the top of the album first - but it is very very slow and there's still almost nothing to render. It refuses to accept the second "Back, it freezes. I have to forcefully close it at this time... It gives a feeling it desperately wants to cache everything instead of executing the user input :)
