saned shouldn't exit. The gphoto2 backend should just return from the sane API
call. It probably doesn't, because it uses "exit(1)".

E.g. if I don't provide a "camera" option in gphoto2.conf and start xsane it
just exits without giving me a chance to select any other scanner that is
available.

Please don't use exit or any other function that ends a program in a
backend. This will stop the frontend immediately, no chance to look for other
backends or close them. Always use "return" with an appropriate status code.

Bye,
