Subject: [PATCH] prefer SIGINFO for statistics if available

A far more appropriate signal for non-quitting interrupts,
unfortunately only available on BSDs (bound to ctrl-T).

Keep fallback to SIGQUIT as support on linux does not seem imminent
:(http://lkml.iu.edu/hypermail/linux/kernel/1411.0/03374.html).
