Do we have a general memory usage problem?  (Note: i'm running a
openwrt-_trunk_ nightly build from a few weeks ago)

Typing 'free' it says:

             total       used       free     shared    buffers     cached
Mem:         28048      15392      12656          0          0       1220
-/+ buffers/cache:      14172      13876
Swap:            0          0          0

14 MB RAM in usage by default?  IIRC that's more than a minimal Debian
system uses!

Attached is the dmesg output corresponding to the emacs kill.

$ cat /etc/VERSION
2011-05-29
$ uname -a
Linux BenNanoNote 2.6.37.6 #1 PREEMPT Mon May 30 20:28:38 CEST 2011 mips GNU/Linux

any ideas?

cheers,

David
