Don't forget lock files.  They are very simple: to lock file "foo",
create a file "foo.lock", and create it in a way that fails if the file
already exists.  This is the original Unix locking approach, and I'm
sure it's possible on a lot of other platforms as well.

BTW, Celeste could very much use locking as well, if it were available.
