replying to myself, after a quick peek at the sources (scheduler.cpp) it
seems they are actually loading the whole thing in memory, so in my case the
backend loads 500K of crap in memory every time I delete something. I am
going to check if there are better ways to do this and if there is a
developer already working on it.
