I think low frustration tolerance is a nice euphemism for emotional immaturity. There should be really no emotion involved when you run into roadblocks. It just gets in the way of finding a way around. Anybody who feels identified with LFT should take some yoga or martial arts and learn to meditate. There is just the way things are and the options you have.
The second trait he talks about (caring about your regexp) is not low frustration toleance. It is perfectionism.
