A delightful way to approach this might involve wp_schedule_single_event.
Grab (and filter) the input you need, then schedule an event to perform the
(potentially long running) function.
You can even schedule another event in the handler, so you can do the work
in a sliced up queue (if it's really that much).
Make sure that whatever you're doing has mid-process results, so you can
display progress on (most likely) your settings page.
For pure awesomeness, create an AJAX handler to provide mid-process results,
