Thanks for your inputs...

Well i still haven't finalized the strategy yet... i just wanted some inputs .. in my case there are thousands of queries and numerous clients. Each query <CLIENT> placeholder which must be replaced at runtime and then fired and outputs compared . I just wanted to separate the query firing and the comparision processes.

Also in the model that u have proposed how do i add support for handling multiple queries,i can use the same strategy as i had used before... 


use strict;
  use threads;
  use threads::shared;
  use Thread::Queue;

  my $maxnoofThreads = 1;

  my @clientList =  qw(client1 client2 client3 client4 client5 client6
+ client7 client8 client9 client10 client11 client12);
  my %hash;
  my $q = new Thread::Queue;
  $q->enqueue(@clientList);
  for(my $i=0;$i<= $maxnoofThreads; $i++)
        {
                $hash{$i} = threads->new( \&worker, $q,$i);
        }
                $q->enqueue("undef");
  foreach my $thr (values %hash)
           {
             # Don't join the main thread or ourselves
             #if ($thr->tid && !threads::equal($thr, threads->self))
             #   {
                        $thr->join;
             #   }
           }



sub worker {
    my( $Q ) = shift;
    my $i = shift;
    while( my $workItem = $Q->dequeue ) {
        return unless($workItem);
        print " workitem  from thread $i -->$workItem\n";
        ## Perform query
        ## Perform comparison
        ## Perform output/cleanup
    }
}
