Hi Christopher, 
I've done further tests.
Regarding your question, effectively after reproducing the problem with the 
previous kernel I've got a crash file from google-chrome. Even with the default 
values mentioned in #3 
What I've observed is: 
- when having swap off the problem arrives faster when reaching the memory 
limit, the system just restart at logon screen (but it doesn't seem a complete 
reset because I didn't get the GRUB screen (more like the lightdm process 
restart?)
- when having swap on the problem arrives when consuming almost all the swap 
memory, but same issue: mouse and keyboard start not to respond and then 
finally restart.
- with the new kernel 3.14 the restart does not arrive but the system become 
equally freeze near the limit of memory and eventually require a hard reset or 
have to wait to be able to kill some of the process (that could take too long). 
But in this case google-chrome started to give unresponsive windows messages 
and kill their own processes himself, giving proper errors.

The steps I use to reproduce the problem are:
- execute $ sudo memtester 2G
- open almost 30 bookmarks of web pages as tabs of google-chrome
- eventually execute $ sudo memtester 1G (when using swap to reach the limit 
again)
