Hmm.  Can you try the same with the latest developer snapshot I just
created?  I found this problem which created undesired DENY ACEs,
maybe this was the reason /knock on wood/.

But there's still the fact that the ACL isn't ordered the way Cygwin
intends to do it.  That points to another problem in ACL creation.
Either the ACL created at file creation time already hinders Cygwin
to set it straight afterwards, or the created ACL is missing something
so sorting fails.

Oh well.
