Hi Stefan, I think I might end up using Minion eventually, but I'm hoping I 
can get away with something quick and dirty for now.  Thanks!  -=>j

Is Minion  an option for you?  By
default it depends on a Pg instance, but I'm pretty sure that there's at
least a SQLite backend available on CPAN as well.

[Mojolicious] Time limit a slow process?

[Jason Crowther]

I'd like to fire and forget a process, but put a timeout on how long that 
process can run.  It's easy enough to kick off a process 
with Mojo::IOLoop::ForkCall (deprecated) or Mojo::IOLoop::Subprocess, but I 
can't find any examples of adding a timeout.

Here's some pseudo code for what I'm looking for:

get '/background' => sub {
my $c = shift;
my $subprocess = Mojo::IOLoop::Subprocess->new;
$subprocess->run(
sub {
# limit how long the following sub should run
doSlowWork();
return 1;
},
sub { # required, even if you don't use it
my ($subprocess, $err, @results) = @_;
}
);
$subprocess->ioloop->start
unless $subprocess->ioloop->is_running;
$c->render( text => q|background process started|);
};

doSlowWork()  doesn't need to return anything (output is polled for 
elsewhere.)

Can someone point me in the right direction?  Thanks!
