# Throttle wrapper around tmux-continuum's save script.
#
# tmux re-renders status-right per client per status-interval, so the
# upstream save script is invoked far more often than it can possibly do
# useful work. This wrapper short-circuits the common case using only
# bash builtins (no fork, no subprocess) and only execs the real script
# when the throttle window has elapsed.
