Code review comment for lp:~jelmer/bzr/mkdir-p

Good job picking up this.

Amusing (though... not actually related), I've just been reading this in the make documentation: "For example, don't use ‘mkdir -p’, convenient as it may be, because a few systems don't support it at all and with others, it is not safe for parallel execution."

Style nit with the code, rather than complicating the simple run() method with nested functions that don't need to close over anything, I'd prefer if they were @staticmethod or something on the class.
