Hehe. Well, this is just one file. I might agree that memcached is 300 lines of relevant pseudocode -- but then again, it's implemented in C, not pseudocode...
I agree that 4k lines isn't that much, but it's an order of magnitude off from 300. And again, that's just for that one single file.
4000 isn't that much either & whats memchached? A hashmap?
He maybe means 300 lines of relevant code (+ ~3700 sugar)
