The folder name I've been archiving e-mails on this subject in is called
I'd also be happy with "non-broken locks"...
I could also be happy with private locks (since in addition to resolving
broken POSIX behavior, they will ALSO allow user space servers to keep
separate sets of locks for each client lock owner - if I remember, the
addition of that capability prompted the private name).

I'm nervous about such close names, but it's easy enough to use grep or
cscope to check a code base for typos in this case.
