What exactly is the role of 'wtpath' in here? Maybe this is explained in
the later patches.

Can we rename the function arguments better? 'a' and 'b' sound very
naive to me. Maybe change these to something more like: 'firstwt' and
'secondwt'? Yeah even this sounds kiddish but you get the idea right? Or
like 'wt' and 'wt_dup'?

Nit: maybe make it 'rm -rf' as that's the popular way of doing it?
Otherwise this looks good to me. But again, we need comments from others
too.
Nicely done! :)
