[Sugar-devel] Browse cache bloat

[Sebastian Silva]

I've implemented the first part of this patch.
It deletes partial downloads when user clicks on cancel button or 
deletes journal download entry.
This should already mitigate thie situation. Alas, the partial download 
still remains when there is a crash.

I could remove partial downloads on start of activity, but i'm worried 
another instance of Browse might be open and downloading.
How should I check for this condition?

Thanks
Sebastian
