AFAIK it is a general M-x behaviour.  Pressing return in the minibuffer 
starts the hourglass, and then invokes minibuffer-complete-and-exit.  
This function throws so the start_hourglass done after return is 
canceled by an unwind-protect (in keyboard.c, command_loop_1(), around 
line 1784).  This may be a bug.  I've checked 21.3 and it is the same 
there so it is not a regression.
