dtourolle 37136f7377 Let one outbox drain run at a time ...

A finished merge drained the outbox and the sync pass that followed
drained it again beside it: each read the 800 MB composite into memory
and sent it, and the later one found its record cleared underneath it
and logged the file as missing. Drains now take a lock and the one that
waited finds the queue empty.
