I need to convert a script that tests concurrent submits against webapps. It uses Coro to ensure multiple submits happened at the same time. Since Coro is unusable these days without patching, I want to switch this over to using multiple processes. But I haven't been able to find any process management module that would allow coordinating the children processes like I do now. This is the code snippet I use now with Coro to do it. Is there a module that will let me do similar with processes? I know I could probably use Mojolicious, but that would require making even more fundamental changes than I'm prepared to at this time. 
# Make all the form submissions happen at same instant. Wait until
# every thread finishes their initial requests and processing before
# submitting.
use Coro 'async';
use LWP::Protocol::AnyEvent::http;
BEGIN { *CORE::GLOBAL::sleep = \&Coro::AnyEvent::sleep; }
my @q = map { async { prepare_requests() } } 1 .. $count;
@q = map { $_->join } @q;
@q = map { async { submit_form(@_) } $_ } @q;
$_->join for @q;
