Not all flags are equal, some applications use a specific set of flags
and another set of applications use another set.  Non-Android apps
won't use the flag that Android added, for obvious reasons.

I still don't see why we'd need to revert this patch due to
regressions in Android.  Maybe I'm really dumb, but I just don't get
it.

Thanks,
