Ring buffer overflow in fb_sdl

I was playing a little with demo on linux and I was able to crash fb_sdl process. I could do it only after suspend/resume of linux host and I understand that this process exists more for testing/development purpose but I have more general question about this crash.

Crash was due to unhandled Ring_buffer::Overflow exception in:

for (;;) input_session.submit(wait_for_event());

What is the proper way to handle such situations?

Should it block on submit call?

Should submit call be wrapped with try/catch and retried after some time?
