Where did you read that Fork Manager works badly with SSH?

About 18 months ago, I was working on a database backup tool that made heavy use of both Parallel::ForkManager and ssh. I did not see any problems with using the two together.

The basic algorithm was: (pseudo-code)

use Parallel::ForkManager;
use Net::SSH::Perl;

$pm = new Parallel::ForkManager(10);

foreach my $server (@big_list)
{
    my $pid = $pm->start and next;
    
    ssh('root@'.$server, '/opt/bin/some_backup_script');
    
    $pm->finish;
}

print "All backups done";
