Comment (by patopaiar):

 Confirming that this is in fact a critical problem breaking down the
 Delete user functionality in this site with ~400,000 users when the
 function attempts to load them all into the selector.

 How to solve this?

 * Paginating results somehow when a large user base is detected?
 * Displaying a search box that fetches specific results? The search might
 result an expensive operation too in a large user base, re-introducing the
 problem trying to be solved.

 I have practically no experience contributing to core, but would be
 interested in helping with a patch if there's interest in solving this
 quite nasty problem in core.
