Comment:

 Marco, Ivan, and I discussed this topic this afternoon. We identified two
 underlying problems:

 1) For each activity launch, we set $HOME. The directory pointed to by
 $HOME is not generally writable by the activity.

 2) Activities or libraries that write persistent files (such as profile
 directories) with restricted group and world permissions will break on the
 second launch because, for all intents and purposes, we never reuse uids.

 We can certainly fix (1) by, for example, setting $HOME <- $SAR/data.
 However, we are all ambivalent about whether this is a good idea because
 we believe it will tend to delay the detection of permission-related
 failures until the second time you launch an activity.
