Question on testing is still standing

[johnhuangclever]

Tested locally using some scripts similar to the original gaprov-worker script:

#!/bin/bash
# test.sh

echo "starting"
node_modules/.bin/coffee test_script.coffee $1
echo "okay"
sleep 3m
echo "done"

# test_script.coffee
console.log process.argv

setTimeout ->
  console.log("done")
, 600000000

Ran locally:

build/gearcmd-v0.8.7-darwin-amd64/gearcmd -parseargs=false -name john -cmd ./test.sh -cmdtimeout 5s -host=clever-dev--gearmand.int.clever.com -port=4730

master build leaves coffeescript processes around:

johnhuang:~/go/src/github.com/Clever/signalfx-metadata-sync$ ps -o pgid -ef | grep coffee

This branch cleans them all up
