call _exit(2) for child process which is safer than exit(3)

As mentioned in the OpenBSD fork(2) man page:

"In general, the child process should call _exit(2) rather than exit(3).
Otherwise, any stdio buffers that exist both in the parent and child will be
flushed twice.  Similarly, _exit(2) should be used to prevent atexit(3)
routines from being called twice (once in the parent and once in the child)."
