It is still an issue, and the reason is the details of how the
hourglass cursor display is implemented on MS-Windows.

I'd like this bug report to be left open, because it is an example of
quite a few other situations where a prolonged operation doesn't cause
the hourglass cursor to be displayed.  I still hope that someone will
add or modify the code to produce the expected effect in those cases.

If someone wants to work on this, I can provide more details.

Thanks.
