here is something which I am hoping is reproducible by others:
download
http://emacsforosx.com/emacs-builds/Emacs-2011-12-23-universal-10.6.8.dmg
save to desktop.
start emacs:
$ ~/Desktop/Emacs.app/Contents/MacOS/Emacs -Q&
create a file that contains the following line many times
asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
$ wc t : 687456 10311840 52246656 t
$ ls -l t: -rw------- 1 x staff 52246656 Dec 23 05:08 t
edit it using the above emacs.
kill all buffers, do M-x garbage-collect
look at the process:
$ ps -vefl | head -1
PID STAT TIME SL RE PAGEIN VSZ RSS LIM TSIZ
%CPU %MEM COMMAND UID PPID C STIME TTY F
PRI NI WCHAN ADDR
before editing the file:
$ ps -vefl | grep 62764
62764 S 0:00.78 0 0 0 2571020 30852 - 0
0.3 0.7 /Users/xxx/Deskt 501 62068 0 5:38AM ttys001 4006
49 0 - ffffff8012762000
after editing it, killing the buffer, and doing M-x garbage-collect
$ ps -vefl | grep 62764
62764 S 0:01.85 0 0 0 2625752 83036 - 0
0.6 2.0 /Users/xxx/Deskt 501 62068 0 5:38AM ttys001 4006
48 0 - ffffff8012762000
I am running on Lion, Macbook Air. does this help?
