+ * IO Error Poisoning:
+ *
+ *
+ * Attempt 1:
+ *
+ * Wrap C calls w/ `ffi`. Most importantly, execute the `close()` through C.
+ *
+ *
+ * Attempt 2:
+ *
+ * Return to using safe-on-the-surface Rust, but attempt to execute the reads
+ * via a separate thread, hoping that the observed poisoning goes away with the
+ * thread being closed and doesn't affect the main thread.
+ *
+ * May need `mpsc` to transfer data without spawning a thread on every read.
