# app_running
# Checks if a specified app is running.
# Note that case does matter: safari is different from Safari
# Note also that this only detects processes owned by your user
# - technically it checks if the process' real-uid is that of your user.
# Thus, for example, it won't detect the 'loginwindow' process since that
# process runs with a real-uid of 0 even through its effective-uid is that of
# your user.
