OK, I found a couple of ways to stop the window manager from freezing, the
best being not to use gdb in Emacs :-(

I set one breakpoint at set_help_echo and another at Fmessage.  I then selected
the TEST menu-item using C-down-mouse-2:

  Echo Area           Stopped location
  C-down-mouse 2 -    show_help_echo       from  command_loop_1 keyboard.c:1535

cont:

  (clear)             show_help_echo       from  command_loop_1 keyboard.c:1535

cont:

 C-down-mouse 2 TEST  Fmessage             from  command_loop_1 keyboard.c:1790

stepping within Fmessage:

 TTTTTTTTTTTTTTTTT    Fmessage             from  command_loop_1 keyboard.c:1790

cont:

 TTTTTTTTTTTTTTTTT

Emacs doesn't hit show_help_echo presumably because execution has advanced
in command_loop_1 from line 1535 to 1790.
