the commit message & comments say "sections", but the code isn't operating on
sections, it's operating on program headers which define "segments". i know
it sounds like i'm being pedantic, but i've seen a lot of ELF parsers that get
confused and use/mix terminology, and it gets hard to untangle the intentions
with the actual code. especially when digging through bug reports.
