--- Comment #4 from Mark Millard <marklmi26-fbsd@yahoo.com> ---
(In reply to rozhuk.im from comment #3)

Looks like I misinterpreted the man page's description
the munmap does return 0 in the example.

Sorry for the noise for that point.

But may be a can make up for it . . .
May be the following example makes the report
clearer?

I ran an a.out built from a source with 16 instead of 4,
so for a 8 GiByte aarch64 system.

Before the a.out run:

Mem: 13M Active 1240K Inact, 108M Wired, 28M Buf, 7757M Free
Swap: 28G Total, 28G Free

After the .aout had finished, from a separate top
run:

Mem: 2197M Active, 4937M Inact, 255M Wired, 186M Buf, 629M Free
Swap: 28G Total, 11M Used, 28G Free

15 minutes+ later with the system left idle: not much change
from what is shown above for the above.
