1) Django has a habit of creating an extra PID which Toaster cannot capture, and which leads to dangling processes and memory leaks.

The solution is to use the "--noreload" option for "runserver".

2) Toaster has a typo in the shutdown code that causes an infinite loop if the PIDs cannot be killed with a simple "-0".

  while kill -0 $pid 2>/dev/null; do
    kill -SIGTERM -$pid 2>/dev/null
------------------^
    sleep 1
  done

Removing the extra "-" results in safe and sane shutdowns.
