unhandled ECONNRESET when using head

[pigulla]

I'm trying to use head to only get the first n bytes of output. See the following (contrived) example:

var procstream = require('procstreams');

procstream('cat', ['/dev/random'])
    .pipe('head', ['--bytes=100'])
    .data(function (err, stdout, stderr) {
        console.log(stdout.length + ' bytes read');
    });

When that code is run, I get an unhandled error event:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: read ECONNRESET
    at errnoException (net.js:901:11)
    at Pipe.onread (net.js:556:19)

I'm not much of a Linux shell guy but I assume head just closes the stream when enough data was read. It would be nice if procstream could handle these kinds of situations.
