Sorry, I'm not sure I understand: are you saying that "C-h H" _will_
display the hourglass cursor on X?  If so, where's the code that
starts the atimer which, when expires, will display the hourglass?
Can you (or someone else) please verify that the hourglass is indeed
displayed on X?

AFAICS, the code which sets this atimer is in start_hourglass.  But if
that is true, all the calls to start_hourglass are made on Windows as
well, and the hourglass should display on Windows as it does on other
platforms.  What am I missing?
