I'm not a big fan of keyword args either, but an optional second argument
that makes it atomic wouldn't kill anybody.

(create-directory pathname [ atomic? ] )

Create the directory specified by pathname.  If the atomic? argument is
present and is true, do this atomically, raising an error if the directory
already exists.  Otherwise, do nothing if the directory already exists.
Raise an error in all other cases where the directory cannot be created.
