Absolutely, thanks a lot for your investigation!
Sounds all reasonable, the symptom, the timeframe, the cause/intention
and the fix.

Will try ASAP and report in case nobody else will have done erlier than
me (which I consider done if I notice a corresponding commit).


Unfortunately, I think there's more discussion to a related topic
needed: The permission mapping.  In real world, I had massive problems
with missing delete bits for 0-mask mapping.  But that's another story
and I forgot many things why/how to better transform permissions into ACEs.

If someone notices/starts such a discussion, please opt me in.

Thanks,

-harry
