where it is said, among other, that NSTableView items may be filled

Tables aren't actually filled with anything. Instead, you provide the

return [NSString stringWithCString:buf length:len
encoding:NSUTF8StringEncoding];
Be aware that this method needs to be *fast*. This might mean caching
your values as they are generated, if possible.
I.e. is it possible to return a NSString without its preliminary
retaining?
Re-read the Cocoa memory management guide.
+stringWithCString:encoding: does not start with allocate or copy,
meaning you don't own it. Therefore you must not release it. Likewise,
the method you're implementing doesn't start with allocate or copy, so
you must not leak ownership of the returned object.
