Sounds reasonable, but the patch looks pretty messy. Can't we create
some common function that would be called both here and on ServerLoop?
We also have sigusr1_handler that starts an archiver -- why does that
one use different conditions? Also, the block at lines 2807ff seems
like it ought to be changed as well?
