In my case, "my_job" does some database queries and decides to call a function that will result in a cross-processor message and then wait for a result to be returned.
I would still benefit from a lot of jobs in parallel if they're just waiting for results from another machine, right? This waiting for outside resources is the basic reason for my wanting to run so many jobs in background.
Am I missing anything, or am I on the right track?

thread::pool::simple
Simple(3pm) User Contributed Perl Documentation Simple(3pm)
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.
