 should be:
 {{{
     A caller will typically perform operations that take locks on some
     of the sharesets returned by this method. Nothing prevents sharesets
     matching the prefix from being deleted or added between listing the
     sharesets and taking any such locks; callers must be able to tolerate
     this.
 }}}
