I was mostly thinking of the 'seq = query(); wait(seq + n);' pattern where we can avoid doing the full update more than once if we enable the interrupt already during the query.
Don't we still wait 5 seconds before disabling vblank? In that case, the chances of hitting an idle vblank are pretty slim if the application is actually busy.
With the disable_immediate thing we only wait until the next vblank before disabling the irq again.
