Basically it's stuff that that's memory-mapped read-only and not currently used. But instead of fully freeing, FreeBSD figures its more efficient to keep it around on a list. It's the same as free memory for all practical purposes, in that if there's no "free" memory, the inactive memory is used before resorting to stealing buffers or using virtual memory.
