This is by no means breaking or disrupting anything on my end (at least that I can tell), but I did notice in
some commit messages a few weeks that someone was attempting to replace vfork with posix_spawn
specifically on macOS, so maybe my system is some unhandled corner-case?
That change is already on master. If your build of a recent master
branch doesn't use the posix_spawn code, the first place to look is in
config.log, where you should try to find the reason(s) why the
configure script decided your system doesn't have posix_spawn.
Thanks.
