I think I'd argue against bothering with getgrouplist at all if we have to maintain a backup to it either way, it just makes the code messier. But I'll leave that part up to you (maybe it's that much faster).

Still a couple of other comments though.

    Same comment about "callback" as from my other review.



src/lib/util/kuser_unix.cpp
<https://git.reviewboard.kde.org/r/116881/#comment37548>

    Not sure what you mean with the comment here. Shouldn't gid_buffer[i] be just as safe (if not more) than obtaining the gid_t* and then dereferencing that as an array?
