TL;DR

The trilogy Ruby C extension acquires a pooled read buffer for each query and only returns it to the buffer pool on the normal success path in execute_read_query_response. When an unexpected exception interrupts a query, such as Timeout.timeout firing while waiting on the socket, the extension shuts the connection down and re-raises without checking the buffer back in, so the buffer is never returned to the pool. Each interrupted query leaks its read buffer, and sustained timeouts let process memory grow until the host is exhausted. The fix releases the buffer before shutting down the socket in the exception paths so memory is reclaimed.
