Bleh. These SIGHUP/log file races are really annoying, and I'm going
to need to trawl the list to see if anyone's proposed a more general
solution. (I keep thinking about assigning an xid as a generation
number to an in-memory configuration...)

For now, is the following test giving us much, or can we remove it?
We've already done the wait_for_log(). If that "sequence point" turns
out to be inadequate for some other reason, we'd have to fix it
anyway.
