Hi Joel,

The RegRead, RegWrite, RegPoll prints generate over 400 lines
per GPU, into the logs. This is too much, especially now that
it's been working for a while.

I'm thinking let's delete these entirely. If we somehow get
into debugging this aspect of the sequencer, we can temporarily
add whatever printing we need, but I think it's one notch too
far for the final product, now that you have it working.


thanks,
