    Increase default IO timeout from 10ms to 5s · 0a1af395

    With the recent changes to the main loop, we no longer have unconditional
    polling.  This means we can now sleep in select() for much longer than we
    previously did.  This patch increases our select() sleep time from 10ms to 5s
    which is effectively unlimited since we're going to wake up sooner than that
    in almost all circumstances.
    
    With this patch, I see the number of wake-ups with an idle dynamic ticks guest
    drop from 80 per second to about 15 times per second.
