About two minutes ago I hit “save” on an unsaved buffer in DrRacketCS on Mac 
running MacOS Catalina 10.15.5, was surprised to see a spinning beach ball for 
a few seconds, then went to the terminal from which I’d started DrRacket and 
saw this:

… this was being generated very very quickly, megabytes per minute, surely. I 
force quit (at the OS level). 

The catch is that I’m running a version of DrRacketCS that dates back to May 
25th, and it looks like some maybe-possibly-related fixes have happened since 
then, so I’ll update and for now this is just an FYI.
