# This is my home-grown solution for implementing the model end of
# a multi-step form in Rails.
#
# There's a step attribute on the model, and the after_step method
# lets me limit validations to only occur after a particular step.
#
# I have to be careful in the controller to make sure the right
# attributes are set at each step, and that the step attribute can't
# be hacked.

The Ruby daemons gem, as used by daemontools, does this to restart daemons:

  @group.stop_all
  sleep 1
  @group.start_all

The stop_all method does not wait for the daemon to exit before returning.

Anyone see the huge glaring problem here? *grumble*
