I built a surprisingly simple proof of concept around the above flow,
and it looks like the idea is valid. There are still bugs to track
down and race conditions to examine, but I don't think it's too early
to call the idea of "BackupPC Green" a success.

Some followup questions:

Does "activeJob" still equal 1 during the link stage? I'm having
trouble catching a backup when it's doing so.

Speaking of "activeJob", I haven't found a way to answer the question
"Are any hosts active?" Using BackupPC_serverMesg status hosts doesn't
work because trashClean always reports itself as active. Is there any
other criterion I could use to examine all possible jobs to see if any
are active? My proof of concept only examined a single host.
