allocate your event struct in the callback as the storage will disapear.

no need to re-run the dispatch call here as the one in main() is the main loop
and will pick up after the return of the callback.

as stated above.. there is no need to call event_base_dispatch() again, so
there wont be a problem. If you really need to go through one pass then
use event_loop()/event_base_loop()
