Oh, yeah.. the problem was that DNS timeouts took too long.  It looks as
though this has already been addressed in /etc/resolv.conf:

     options  Allows certain internal resolver variables to be modified.  The
              syntax is
                    options option ...
              where option is one of the following:

 [items removed]

              timeout:n
                        sets the amount of time the resolver will wait for a
                        response from a remote name server before retrying the
                        query via a different name server.  Measured in sec­
                        onds, the default is RES_TIMEOUT (see <resolv.h> ).

              attempts:n
                        sets the number of times the resolver will send a
                        query to its name servers before giving up and return­
                        ing an error to the calling application.  The default
                        is RES_DFLRETRY (see <resolv.h> ).
