From d17b33131c14864bd1eae275f49a3f148e21cf29 Mon Sep 17 00:00:00 2001
From: Leo Chan <leochanj@live.unc.edu>

Subject: Squashed commit of the sb-vbs branch.

Includes the SD-VBS benchmarks modified to:
- Use libextra to loop as realtime jobs
- Preallocate memory before starting their main computation
- Accept input via stdin instead of via argc

Does not include the SD-VBS matlab code.

Fixes libextra execution in LITMUS^RT.
