About five people tested the make(1) binary with -DUSE_KQUEUE,
when I asked, and reported no lockups.  The make(1) built with
kqueue(2) did not result in any good/bad change in buildworld
times, so I felt like switching to this mode wasn't necessary.
In any case, I think the status for this item can safely
migrate to status.done now.
