Obviously where it goes is not a big deal. But I think it's clear that it
has everything to do with ptrace and nothing to do with anything else.
It resolves a situation that can only arise because of ptrace magic.

Or just recognize that this trivial wrapper around == -1 has little
value two lines away from a place where = -1 is done explicitly.
Really, the "abstraction" is more confusing than not in this function, IMHO.
