Because we need to distinguish in between situations where a function was really not executed (counter == 0) and the situation where we miss profile for a function. One another solution could be the usage of gzip that can shrink file sizes ~10x. That will be beneficial in situation where you don't merge profiles. How exactly do you merge profiles? Do you run parallel invocation which can take log2(N)?
