    What does the timeout measure? The time while no data was coming? Can the 
protocol send heartbeats if no data is available?
    
    Would it be simpler to switch to TCP as the coordinator protocol? It has 
keepalive messages integrated and it throws an error on the reader side if the 
connection is closed by the sender. Would that cover it?
    
    A shutdown hook is a good idea. Make sure you also remove the shutdown hook 
in `close()`, otherwise you have a resource leak in the JVM. Take a look at the 
`BlobServer` and its `shutdown()` method for an example of how to do this 
robustly.

> A general purpose API to run operators with arbitrary binaries. 
> This will allow to run Stratosphere programs written in Python, JavaScript, 
> Ruby, Go or whatever you like. 
> We suggest using Google Protocol Buffers for data serialization. This is the 
> list of languages that currently support ProtoBuf: 
> https://code.google.com/p/protobuf/wiki/ThirdPartyAddOns 
> Very early prototype with python: 
> https://github.com/rmetzger/scratch/tree/learn-protobuf (basically testing 
> protobuf)
> For Ruby: https://github.com/infochimps-labs/wukong
> Two new students working at Stratosphere (@skunert and @filiphaase) are 
> working on this.
> The reference binding language will be for Python, but other bindings are 
> very welcome.
> The best name for this so far is "stratosphere-lang-bindings".
> I created this issue to track the progress (and give everybody a chance to 
> comment on this)
