 As I said in an earlier comment to this PR, I support this change,
 but I don't think it is related to the present issue.

 It did not.  Console log:
 
   http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2016/2016.12.13.19.03.49/install.log
 
 Timestamped log:
 
   http://www.gson.org/netbsd/bugs/51531/install-2016.12.13.19.03.49-slog.txt
 
 Some observations based on the timestamped log:
 
 The "ifconfig -w 15 -W 5" command runs in five seconds.  The ftp
 command then takes some 74 seconds to time out.
 
 Then, a diagnostic "ifconfig -a" is run, and it shows a TENTATIVE flag
 even though 83 seconds (!) have now elapsed since the "ifconfig
 -w 15 -W 5" started.
 
 Ten seconds later, a second diagnostic "ifconfig -a" is run, and then,
 the TENTATIVE flag is gone.
 
 When reading the timestamped log, note that the console output is not
 being read during the 10-second sleep between the two "ifconfig -a"
 commands, so the output from the first "ifconfig -a" only appears in
 the log after the second "ifconfig -a" has been sent, and its timestamp
 is not meaningful.  The timestamps on the "send(..., 'ifconfig -a\n')"
 lines are correct.
