in thread copy perl and some modules into an offline OS

You're doing things backwards

use a root prefix, like /inside

build all your stuff relative to /inside, all the software

then make a jail ANYWHERE

then copy /inside into jail

inside the jail treat /inside as root

or if you want /usr/bin .. instead of /inside/usr/bin

start copying /usr/bin ... into your jail

then go to jail, switch to jail, chroot to your jail ,

then install perl as normal into whatever place inside the jail, using absolute jail paths

see links for chroot setup

[Corion]: marioroy: Oh, that's always cool, having API-compatible modules. This makes testing and comparing things much easier
[marioroy]: IPC in MCE::Shared can handle 400k (sends) per second. That's seems a lot for being a pure-Perl module. After making the release, will come back and post a solution for a node by a fellow wanting faster logging.
[Corion]: While working on WWW::Mechanize:: Chrome, I had the suspicion that AnyEvent was doing something wrong, but I was able to swap it out for Mojolicious and the error persisted.
[Corion]: Of course, the error was in my own code ;)
[marioroy]: Corion, start and start_child in MCE::Hobo::Manager return a MCE::Hobo object, whereas P::FM returns the PID. I can have it return the PID though. I tried Hobo::Manager with several P::FM modules, just changed P::FM to MCE::Hobo::Manager and it works.
[marioroy]: I also have a Hobo driver for Forklift allowing folks to use in multiple classes, no conflicts with one another. That's not possible for P::FM.
[Discipulus]: congrats marioroy!
[marioroy]: CORE::wait works well eventhough multiple instances or classes using Hobo::Manager.
[Corion]: marioroy: I'm not sure what the normal use for the PID is in P:FM, but I guess that most programs just ignore or log it
[Corion]: Oh, yes, programs could call wait $pid, but if your $pid is an object, then you could add a ->wait method to it and wait $pid would call that automatically "thanks" to indirect object notation
