Unicorn uses the USR1 to indicate that log files should be reopened. This commit implements the same functionality for our forked sidekiq workers: - USR1 is intercepted in the unicorn master, and re-issued to all child processes - USR1 is trapped in the sidekiq processes, and `Unicorn::Util.reopen_logs` is used to re-open log files
