------------------------------------------
Hi Doug, the patch in H-1869 implements the policy of requiring read-permission
to set the access time and requiring write permission to set modification time.
This works in some use-cases. However, this is different from the POSIX
standard.
I would like to get this resolved before shipping 0.19, hence marking it as a
blocker.
