Factor in buffers and cache to memory usage #14

Closed gregsexton closed 9 years ago

The way you're calculating memory usage on linux is slightly misleading. This change will use the relatively new MemAvailable info if it is in /proc/meminfo otherwise we fall back to adding in buffers and cached (which is a technique that is a little outdated now but should give a more useful picture).

I quickly found these links which might help explain this, if you're unfamiliar.
