recv throws except for EAGAIN
should also allow error codes such as ETIMEDOUT, EFSM

The wrapper is not usable for the survey pattern, as it returns EFSM right now (should be ETIMEDOUT, see: nanomsg/nanomsg#194).

There's only a single exception type. Catching it on deadline expiration may also catch a fatal error.
There's no way to distinguish between them.
