Weird 'free' output

[Omer Zak]

>From man free:

available
              Estimation of how much memory is available for starting
new applications, without swapping. Unlike the data provided  by
              the  cache  or free fields, this field takes into account
page cache and also that not all reclaimable memory slabs will
              be reclaimed due to items being in use (MemAvailable in
/proc/meminfo, available on kernels 3.14,  emulated  on  kernels
              2.6.27+, otherwise the same as free)
