On linux, syscall __NR_exit_group if present, otherwise __NR_exit instead On other platform, call _exit provided by libc The linkage error on Darwin is left unchanged
…or macos macos marks vfork() as deprecated without providing any alternative way to create processes. posix_spawn() doesn't work since it returns ok even if the process fails to run in situations like, file not found, permission denied and so on. We must use another extra pipe to retrieve the status of sub process after fork(). This is how we do in this commit Also fix bug introduced in 2b50a25 wrong implemention of posix_process::operator=(posix_process&&)
