 Currently, the timeout for a given DNS exchange is dictated by
 NameChangeTransaction::DNS_UPDATE_DEFAULT_TIMEOUT which is a constant.  It
 should be configurable, probably at the DnsServerInfo level.

 Other candidates to consider:

 In d2_cfg_mgr.h:
 {{{
     /// @brief Reverse zone suffix added to IPv4 addresses for reverse
 lookups
     /// @todo This should be configurable.
     static const char* IPV4_REV_ZONE_SUFFIX;

     /// @brief Reverse zone suffix added to IPv6 addresses for reverse
 lookups
     /// @todo This should be configurable.
     static const char* IPV6_REV_ZONE_SUFFIX;
 }}}

 From d2_queue_mgr.cc:

 {{{
 // percent.  This is an arbitrary choice. @todo this value should
 // probably be configurable.
 size_t threshold = (((queue_mgr_->getMaxQueueSize()
                      * QUEUE_RESTART_PERCENT)) / 100);

 and then also this:

 // @todo This method assumes only 1 type of listener.  This will change
 // to support at least a TCP version, possibly some form of RDBMS listener
 // as well.
 reconf_queue_flag_ = false;


 }}}
