stat(5) specifies exclusive-access files, which we do use for locking.
In what sense is that not `doing locking'?  It's not POSIX byte-range
read- or write-locking per fcntl, but it's not clear to me how often
that's actually useful.  In quite a few situations, having a single
process directly access a resource and forcing all other accesses
through that process suffices.
