Ah, I wanted to reply to my original email. I was wrong.
There's a cancel event that lasts a long time according to Procmon, but it
seems to last as long as the racket executable is running. I don't think
it's the source of any performance problem.
So, yeah... carry on, nothing to see here.
Thanks,
Dan
