- add conf.gem line to
build_config.rb

- NOTE: POSIX timer not available on MacOS
# Specify signal name if you want (default ot SIGALRM as timer_create's default)
# signal: nil will send no signal.
# you can add handlers with mruby-signal or mruby-signal-thread

# You can create multiple timers (and are thread-safe by kernel)

# ...- POSIX timer with interval
# recommended mruby-signal-thread
SignalThread.trap :USR2 do

end
timer = Timer::POSIX.new(signal: :USR2)
# Invoke first timer after 5,000 msec,
# then start interval timer every after 3,000 msec
# like uv_timet_t or timer_create API
timer.run 5000, 3000
