+ *

+ * mean data loss: we've read data but now we can't write it out.
+ *
+ * We try to use pread() and fall back to regular read() if the source fd
+ * doesn't support positional reads, for example when it's a pipe fd.
+ *
+ * If we get EAGAIN when writing to the target fd, we poll() on it until
+ * it becomes writable again.
+ *
+ * FIXME: If we get a write error when use_pread==1, it should be safe to
+ * return the number of sent bytes instead of an error because pread()
+ * is, in theory, idempotent. However, special files in /dev or /proc
+ * may support pread() but not necessarily return the same data on
+ * successive reads.
+ *
+ * FIXME: There is no way now to signal that we managed to send *some* data

+ * continue searching.
