Will Ultrix free() ever learn to reset brk() to free memory?

Notice that (on Ultrix 3.1 at least) the malloc man page says for
free:
The argument to free is a pointer to a block previously
allocated by malloc. This space is made available for further
allocation, but its contents are left undisturbed.
I think it's historical and has something to do with the way malloc,
free, and realloc work/interact. This is also what the man page says
for 4.3bsd, so I guess 4.3bsd isn't a "nice Unix system" either.
