env-update has an option "--no-ldconfig" that doesn't exist for env.eselect. It should be easy to implement this.
Created attachment 114682 [details, diff] Proposed patch for env.eselect
No reaction since 10 weeks, in spite of the proposed patch. :( So I think we are going to ship our own env-emacs.eselect module with app-admin/eselect-emacs that provides us with the needed functionality.
Fixed as of 1.0.10
