I figured out what was going on.  Though RedHat neglected to mention
this in the upgrade docs for RedHat 7.0, sending a SIGHUP no longer
works to have the [x]inet daemon refresh its configuration.  You now
have to send a SIGUSR2.  Once I tumbled onto that nice little
incompatibility, it was a simple task to get things working again.

Thanks to those who (privately) reminded me about the tool lsof.
