Comment (by robert):

 Replying to [comment:3 cehoyos]:
 > Did you test above patch?
 > Isn't open() refusing to open files if the user does not have the
 relevant permission himself?

 Hi cehoyos, I know it's odd but on Android you find those permissions,
 maybe because every app runs on its own sandbox with its own user, so it
 wouldn't make sense to make the files owned by a single user. I don't
 know, it's just an idea...

 Regarding your question about open()... it won't fail if "others" have
 read permission even when the "owner" has no read permissions. If you
 think your patch is better it's ok, I'm mostly a java programmer and I
 don't know much about the C apis.

 Thank your for your fast response.
