I'm got this gem setup in my Rails app, but it doesn't seem to catch errors inside of Rake tasks:

task :cron_task => :environment do
  raise "error in cron task"
end

doesn't report anything on Ratchet, but this works:

task :cron_task  => :environment do
  begin
    raise "error in cron task"
  rescue Exception => e
    Ratchetio.report_exception(e)
  end
end

Is this by design? It looks like this gem taps into some Rack middleware to catch exceptions which would explain why it doesn't work for Rake tasks, is there a recommended way to have it catch all my Rake tasks?
