--- Comment #3 from Maxim Konovalov <maxim@FreeBSD.org> ---
Hello,

This is not specific to FreeBSD.  Upon process termination, both voluntary =
or
involuntary, the whole address space including the heap of the process is
destroyed.  So, it is quite common for simple utilities like echo(1) with s=
hort
life cycle to rely on this.  I think pretty much any book of unix programmi=
ng
covers that.  My personal recommendation is Steven's "Advanced programming =
in
the UNIX environment" aka APUE.

I'm going to close this ticket unless you have any concerns.

Maxim
