Yes. I think gold's convention is to use $method for public methods, and
do_$method for protected virtual methods that implementations
override/provide. I've seen "do_" used for the same purpose in other
projects too. (IIRC, gold is even stricter and requires that virtual
methods must be protected, thus mandating that design everywhere.
Grep for "this->do_".)

Yeah, unistd.h is included in defs.h, so it most probably
won't be an issue in practice.

Given the above, no need to wait.
