.. not supposed to be processed.

That was a misunderstanding.  On X the frame is not redrawn either.

The difference was that on Windows, when waiting, the mouse cursor
remained invisible while on X it became visible again.  Your patch fixed
that already.  I didn't believe you could (reasonably) redraw the frame
while waiting for a subprocess, but you somehow sounded optimistic ...
