I'm in the throes of implementing changes that push umask processing down
into individual file systems, permitting UFS ACLs to override the umask
using the ACL mask, which would reproduce the Solaris/Linux model
(non-POSIX.1e).  However, there are some interesting implementation
question shtere, so it will probably be a bit (perhaps a couple of weeks)
before I have a useful prototype worth reviewing.  I agree that those
semantics are useful, however :-).
