STINNER Victor added the comment:

Instead of just catching EAGAIN, you can catch BlockingIOError. In Python 2.7, 
it means catching: (EAGAIN, EALREADY, EINPROGRESS, EWOULDBLOCK) errors.

I made a similar change in asyncore recently:

Issue #16133: The asynchat.async_chat.handle_read() method now ignores
socket.error() exceptions with blocking I/O errors: EAGAIN, EALREADY,
EINPROGRESS, or EWOULDBLOCK. Initial patch written by Xavier de Gaye.

This issue is another reason to not use eventlet with monkey-patching :-) It's 
time to switch to asyncio (trollius for Python 2)!
