ubuntu 32 bit vm. Latest Pharo20. Generation works pretty much as expected, but
I've been letting the compilation (after hitting "accept" in the changes
browser) running for about 45 minutes and it's still not finished. Looks like
some kind of infinite loop but I can't interrupt.
I checked vmstat to see if memory / swapping might be an issue but there's more
than enough memory available. I'll keep checking.
