[zeromq-dev] hitting file descriptor using gevent

[Tim Cooijmans]

It does sound more reasonable, yes. I'm still doubting whether a single PUSH
PULL socket per process for sending and another socket (either PUB SUB or
normal TCP) for confirmation wouldn't be a better option. Making thousands
of connections between the same endpoints feels like a stupid thing to do.

Pair of 0MQ sockets with a single TCP connection between them consumer 3
file descriptors on each peer. One for the TCP socket itself, two for the
socketpair used by the 0MQ socket for internal eventing.

1024/3 = 341. That sounds more reasonable than 70.
