sometimes fails to start up

[HarlanH]

Logs seem to suggest that it's a race condition, where keenCountFn isn't able to populate keenCount on startup before the query tries to access it in keenCount[docs[d].url], causing a fatal error.

Solution might be as simple as to initialize keenCount on declaration, but I'm not sure.
