sw_sync: Wait until the end

If we allow a fork-helper to exit normally before the parent tries to reap the helper (fork-helpers are intended to be only used for persistent background loads), then the helper unhelpful aborts because the child exited cleanly.

Simplify by not using the so called helpers at all.

Accidentally pushed, but worksforme so I hope no one notices.
