When CancelIoEx returns ERROR_NOT_FOUND, the overlapped read has already completed. Previously the buffer was restored without updating its length, so the bytes the kernel read were silently discarded. Call notify_completion instead, which reads the byte count from the OVERLAPPED structure and updates read_buf accordingly. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Closing this PR as I am not in a position to vouch for the putative fix. See "AI Caveat" in #450 for details. |
