Some notes on remote debugging mac builds on Travisci.  It's hard to tell when something hangs what the cause it. Trial and error via commits is tedious. And on Mac , sometimes it's the gui asking for input. So I worked my around to get the access I needed for faster debugging a build.

#################################################
# Enable remote ssh access to travisci build for debugging

# Add a key so we can login to travisci vm

An experimental change for fast Clojure REPL startup:

1. Download the JAR: clojure-1.8.0-fast.jar
2. Launch it via java -jar clojure-1.8.0-fast.jar

The code used to create this JAR is on GitHub.

What's it doing?

It is:

# Returns any output produced by the command (stdout or stderr) as a String.

# If you've got a cleaner way of doing this, I'd be interested to see it.
# If you think you can do it with Ruby's Timeout module, think again.
