clojure-1.5 to 1.6
runner/process_manager for slow processes/computers

* The first time when you execute a process this runner asssumed the
  process starts within 5 sec w/ blocking. Now it can wait forever w/o
  blocking.
* When you trigger quickrun before previous execution finished, this
  runner simply ignore previous attempt and starts next one immediately.
  Now it cancels next attempt until previous execution actually
  finishes.
