More whimsy from "man sbrk" on Solaris 10:
The use of mmap(2) is now preferred because it can be used

From Wikipedia:
sbrk and brk are considered legacy even by 1997 standards (Single UNIX
Specification v2 or POSIX.1-1998).[5] They were removed in
POSIX.1-2001.[6]
On a whim, I checked a couple of boxes around here (I haven't used sbrk()
since malloc() came along):
Mac:
The brk and sbrk functions are historical curiosities left over
from ear-
lier days before the advent of virtual memory management.
FreeBSD:
The brk() and sbrk() functions are legacy interfaces from before the
advent of modern virtual memory management.
Both of them come right after the DESCRIPTION header.
