it should still fix some issue The IPC::Run has support for various timeouts and timers, which should also work on Win32.
Basic:
use warnings;
use strict;
use feature 'say';

use IPC::Run qw(run timeout);

my $out;

eval {
    run [ qw(sleep 20) ], \undef, \$out, timeout(2) or die "Can't run: $?"
};  
if ($@) { 
    die $@ if $@ !~ /^IPC::Run: timeout/;
    say "Eval: $@";
}
use warnings;
use strict;
use feature 'say';
use IPC::Run qw(run harness timeout);

my $out;
my @cmd = qw(sleep 20);

my $h = harness \@cmd, \undef, \$out, timeout(2);

HANDLE_RUN: {
    local $SIG{BREAK} = sub {
        say "Got $_[0]. Terminate IPC::Run's process";
        $h->kill_kill;
    };  

    eval { run $h };  
    if ($@) { 
        die $@ if $@ !~ /^IPC::Run: timeout/;
        say "Eval: $@";
    }
};

To fix the issue you can do The useradd must be run as root, so you will need sudo to specify that nginx can run your script as root.
Be extremely careful with this stuff; make sure you sanitize user names and escape your command properly as well using escapeshellarg().

seems to work fine there is a timeout function but I think what you need can be replicated with read
read -t 10 -p "press any key to continue: " || true
