They aren't quite that bad.  More like 220K for both of them combined
(static bloat of text size; their shared library and/or memory footprint
may be worse).  This is up from 180K in RELENG_5 and IIRC 150K in
RELENG_4.  "optimizing" these libraries by compiling them with -O2
cannot help.

220K is still disgusting, since it is more than twice the size of the
whole stripped file /bin/sh (90K) in FreeBSD-1.  (I have to use the
file size for comparison with old binaries since `size' is broken on
aout format.)

The file size in FreeBSD-2 was only 270K IIRC.  This was with aout and
its extra padding, and with libedit and possible /etc/passwd support,
and even with builtin printf, so it had more features than now!

Omitting /etc/passwd support (just 1 getpwnam() call) as well as history
reduces the text size by another 350K.  Its file size, for essentially
the same features as the FreeBSD-1 sh, is 285K (the full reduction is
from 1059K, giving a total reduction of 774K).  (I have to use the
file size for comparison since `size' is broken on aout format.)  In
FreeBSD-5, the reduction is to 170K.  malloc() is responsible for many
of the extra 115K.

Not too much fun to watch the bloat.  I notice it more since I use static
linkage for everything except ports.  A 64MB root partition is barely
large enough for static everything and 6 kernels.
