In addition to recently releasing Filesys::Virtual::Chroot I’ve also decided to publish my fork() control library as Proc::Fork::Control.
Proc::Fork::Control is a simple to use library which functions much the same way as Proc::Fork. That said, Proc::Fork is not used, as fork() is accessed directly.
Proc::Fork::Control allows you to manage forks, control number of children allowed, monitor children, control blocking and nonblocking states, etc.
This library can be obtained here: Proc-Fork-Control-1.4.tar
Or from CPAN directly:
sudo cpan Proc::Fork::Control
