You're welcome to your opinion, so far I do not share it.  One example: I've 
hit several times in the past where compiling something killed my box and 
made it unresponsive.  I would have loved it for something to have bailed me 
out of those situations.

I've been testing it on a laptop with only 4gb ram, and it's been working 
well for me so far.  Though I honestly think I've not yet hit any thresholds 
, primarily only doing local package builds and web browsing.  

Also, you might want to double-check your math and the configuration values 
in account here, my default earlyoom config is set with -m 4 value, and your 
comment does not take into account swap (default is threshold of 10% free).
