Not for indent-region (it should be IMHO).  Ediff-buffer is quite fast
on my machines, so I can't tell.

I think the easiest way to find out whether the hourglass could be
shown in the context of some function is to put a breakpoint on the
place where the hourglass timer is set up.  Then you will know if
Emacs arranges for the hourglass even if the operation itself is fast
enough so that no hourglass is actually shown before it finishes.

(It might be necessary to change the default handling of SIGALRM by
GDB, in order to run this under GDB.)

This does not always work, as in the case of M-x indent-region versus C-M-\. Both starts the hourglass timer, but the first stops it directly afterwards.
