Long running tasks are blocking others from running? #45

hello:japan should run every second but it looks like it's being blocked to run every second by hello:world

Clockfile:

using RubyClock::DSL

every('5 seconds') do
  rake('hello:world')
end

every('1 second') do
  rake('hello:japan')
end

hello.rake:

namespace :hello do
  task :world => :environment do
    Rails.logger.info "hello world #{Time.now}"

    sleep(10)
  end

  task :japan => :environment do
    Rails.logger.info "hello japan #{Time.now}"
  end
end

Logs:

Closing. I just figured out that rake is blocking and I can use rake_async:
