Aha. No boxes were checked on the "View -> Check Syntax Mode" menu. I
don't know what Check Syntax was doing.

What does it mean if DrRacket's online Check Syntax indicator is blue,
and the tooltip says "Online expansion running", but CPU is 0%.
I can run the code. I can leave DrRacket idle for a long time, but
the indicator stays blue. Disabling and then re-enabling online Check
Syntax doesn't help. Quitting and restarting DrRacket doesn't help.
A wild guess is that Check Syntax is secretly giving up, due to the
"require"s in this module (the size of the "require"-d stuff, or the
complexity of the "require" graph). There's not much crazy syntax
transforming happening in the application code, if that matters.
