The only way to really keep an accurate time in that case would be to
discharge the capacitor immediately after video DMA ends, or to do it
during the small time frame when the 7800 doesn't do DMA (the last few
and first few scanlines iirc from maria.txt)  Of course, you'd need a
way to know when you're in that part of the tv frame...
