> Thanks, I'll look into both of those.
It looks like both are blocked by the catalog operation:
1. refresh: frontend is cancelled, but it still waits on the backend 
RESET_METADATA request to finish in ClientRequestState::BlockOnWait. Still 
looking into why; the right thing here probably is to - after CancelExecRequest 
- also send a Cancel operation to catalogd for the query ID, which would need 
to have some way to identify what operations are on-going for a query ID and 
interrupt them.
2. describe: appears to fail to interrupt loadWithCaching. That should be 
easier to fix. We use a library called Untinterruptibles that we probably need 
to stop using.
