 The first attempt locked the machine up hard and there was only one line
 in "Xorg.0.log".  It was not helpful.
 
 After rebooting and cleaning up, logging in via SSH and running the X
 server under 'gdb' seems to have worked.  The display is properly
 initialized, mouse and keyboard respond.  Clients can connect and display.
 
 First 'twm' was launched with:
 
   $ twm -display :0 &
 
 Then, from the 'twm' menu, 'xterm' was launched.  Using the XTerm,
 'xrdb -merge .Xresources' was run.  The XTerm was closed and a new
 one opened, reflecting the preferences in .Xresources.
 
 The XTerm was closed, and 'twm' told to exit via its menu.  Immediately
 the display froze.  The 'gdb' session reported:
 
 [...]
