# use this module to defer actions to the after-commit hook. this is useful if you want
# to trigger actions in after_create, after_destroy and after_update callbacks but want
# to execute them outside of the transaction (for example, to avoid deadlocks).
# 
# Usage:
# after_create :my_hook
# def my_hook
#   execute_after_commit { puts "This is called after committing the transaction. "}
# end
