Maybe you can live with a kernel that fails to free memory
when we have lots of it, but I know _I_ and a lot of other
folks can't. I agree with the second part though ;)

You can't reproduce it unless:
- you have an awful lot of memory (>128 MB???)
- set the settings for the {page,buffer}out-weight in
/proc/sys/vm/swapctl low enough (something like 512
for your machine???) so that kswapd scans less than
all memory on one try_to_free_page()
Basically, when you have more memory than is scanned
in one try_to_free_page() turn, you can run into the
problem I described...
I hope I have explained the problem now.
