Is it shown for indent-region?
Not for indent-region (it should be IMHO).
Are you sure? I thought it was command-agnostic (i.e. it simply displays an hourglass if more than X seconds have passed since Emacs was last ready to process keyboard input).

Duh! You're right. Hmm... how does this thing work?
I only tried M-x indent-region. For that no hourglass is shown. But if invoked with M-C-\ an hourglass is shown. Turns out that M-x ... calls minibuffer-complete-and-exit, and that function throws so the start hourglass action is unwind and canceled. A bit inconsistent here.
