Yes, the attribute cache timeout is 1s by default, but is settable
with "attr_timeout=T" option.  It can be set to zero to completely
turn off attribute caching.

That would solve the possible worries with access control as well.

The thing with hard links is that the fuse highlevel lib "cheats" and
actually treats different directory entries as different objects, even
if they have the same inode number.  This has a side effect of not
correctly refreshing the attributes on aliases.
