Sorry, but I forgot to mention that EAGAIN is not a good value
to use because it's used by the network system calls for other
meanings (interrupted by a signal).

So if we stop doing the translation then we also need to pick
a different value, perhaps E2BIG or something similar that have
no current use within the crypto API or network API.
