+cannot drop a connection itself, only send a close and wait for the server's reply.
+Without flow control QuestDB reads that close only once the query has finished or

+the closing handshake, after 60 seconds in Chromium. When the bound expires, a query
+ended with `query.cancel()` fails with `QwpEgressQueryCancelTimeoutError`; one already
 released by its timeout or by breaking out of `for await` keeps the error it was
 released with. A reconnecting session, the default, opens a new connection for the
 next query instead of failing. This client-initiated replacement emits `disconnected`
