/var/tmp in FailureDetector

[aaron morton]

I was reading through some code and noticed the following in 
FailureDetector.dumpInterArrivealTimes()

            FileOutputStream fos = new FileOutputStream("/var/tmp/output-" + 
System.currentTimeMillis() + ".dat", true);

If this is meant to be cross platform I'm happy to create a bug and change it 
to use File.createTempFile() . 

Also I could not find any use of the  dumpInterArrivalTimes(InetAddress ep) 
overload. Anyone know if it should be kept?

thanks
Aaron
