Description
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.
