I get this error on trying the README example. Is it related?

julia> zmqparse(req, "2")
read: end of file
 in read at io.jl:351
 in zmq_deserialize at /Users/rahul/.julia/ZMQ/src/zmq_serialize_julia.jl:26
 in zmqparse at /Users/rahul/.julia/ZMQ/src/zmq_client_julia.jl:29

On the server side:

➜ juliatry ../julia/julia server.jl
Reporting this error to the client: read: end of file
Reporting this error to the client: read: end of file

Also, the README examples only work with:

require("ZMQ")
using ZMQ

at the beginning. Else:

➜ juliatry ../julia/julia server.jl

The "using ZMQ" issue is due to recent changes in Julia's require/include. I've updated the code, it will go away once I push the changes to metadata (waiting to fix the other bug, below)

The read: end of file issue is real, probably caused by recent changes to Julia's IO subsystem. I'll create a new issue for this.
