a Linux-like free(1M) would probably not be a bad thing
0%
Description
Over time, users tend to ask how they discover how much free RAM, virtual memory, etc, they have.
The answer being vmstat(1M) often disappoints. I can't think of any immediate reason that a Linux-like free(1M) would be a bad idea, or problematic to implement (though making it do sensible things with zones might complicate things at least somewhat).

How do you convince people that free memory is wasted memory?

Do you mind something like old prtmem plus maybe swap info (where output almost the same as memstat from mdb), or exactly free(1M) port?
