Gracious and Knowledgeable Monks,

I'm dealing with an application with two use cases; a case called "Add" that adds data to a database and a case called "Run" which acts on the database. I want the run instance to be such that when new data is added via "Add", it is enqueued immediately to a thread queue which the main processing loop pulls from.

I have a lock file containing the Run instance's PID and I'm able to signal from Add that new data has been added. However, I wish to defer the operation of catching the signal and enqueueing new data to a thread whose body looks like something of the following: 

sub receive {
   while (1) {
      $SIG{INT} = sub {
         # enqueue new data and stuff
      };
      sleep;
   }
}

This would add data to a thread queue which the main processing loop would draw from. Is there a way (module) to defer signal handling to a process's thread?
