=head1 EXPORT WORKER FUNCTION
=head2 register_function($function_name, $callback_coderef);
=over
=item $function_name
worker process function name.
client process specific this functin name.
=item $callback_coderef
client process call the function, execute thid $callback_coderef.
$callback_coderef's first argument is a client request parameter.
=back
=head2 cascade($function_name, $args);
call self worker function.
=over
=item $function_name
worker process function name.
=item $args
worker argument.
=back
=head1 USAGE
=head2 my $worker = Your::Worker->new(\%opts);
=over
=item $opts{address}
worker process listen address.
=item $opts{timeout}
seconds until timeout (default: 10)
=item $opts{max_workers}
number of worker processes (default: 0)
if max_workers is 0, worker start single process mode.
if you specific max_workers Zero or more, do prefork worker process.
=item $opts{spawn_interval}
if set, worker processes will not be spawned more than once than every given seconds.
Also, when SIGHUP is being received, no more than one worker processes will be collected every given seconds.
This feature is useful for doing a "slow-restart".
See http://blog.kazuhooku.com/2011/04/web-serverstarter-parallelprefork.html for more information. (dedault: none)
=item $opts{max_reqs_per_child}
max. number of requests to be handled before a worker process exits (default: 100)
