    Summary: rio allows a use-after-free buffer access when a future is leaked

    Details: When a `rio::Completion` is leaked, its drop code will not run. The drop code is responsible for waiting until the kernel completes the I/O operation into, or out of, the buffer borrowed by `rio::Completion`. Leaking the struct will allow one to access and/or drop the buffer, which can lead to a use-after-free, data races or leaking secrets. Upstream is not interested in fixing the issue.
