NAME

       Thread::Pool::Simple - A simple thread-pool implementation

SYNOPSIS

         use Thread::Pool::Simple;

         my $pool = Thread::Pool::Simple->new(
                        min => 3,           # at least 3 workers
                        max => 5,           # at most 5 workers
                        load => 10,         # increase worker if on average every worker has 10 jobs waiting
                        init => [\&init_handle, $arg1, $arg2, ...]   # run before creating worker thread
                        pre => [\&pre_handle, $arg1, $arg2, ...]   # run after creating worker thread
                        do => [\&do_handle, $arg1, $arg2, ...]     # job handler for each worker
                        post => [\&post_handle, $arg1, $arg2, ...] # run before worker threads end
                        passid => 1,        # whether to pass the job id as the first argument to the &do_handle
                        lifespan => 10000,  # total jobs handled by each worker
                      );

         my ($id1) = $pool->add(@arg1); # call in list context
         my $id2 = $pool->add(@arg2);   # call in scalar conetxt
         $pool->add(@arg3)              # call in void context

         my @ret = $pool->remove($id1); # get result (block)
         my $ret = $pool->remove_nb($id2); # get result (no block)

         $pool->cancel($id1);           # cancel the job
         $pool->cancel_all();           # cancel all jobs

         $pool->join();                 # wait till all jobs are done
         $pool->detach();               # don't wait.

DESCRIPTION

       "Thread::Pool::Simple" provides a simple thread-pool implementaion without external
       dependencies outside core modules.

       Jobs can be submitted to and handled by multi-threaded `workers' managed by the pool.
