IPC::Cmd seems to use either IPC::Open3 or IPC::Run
The IPC::Run docs say -

start() pauses the parent until the child executes the command or CODE reference and propagates any exceptions thrown (including exec() failure) back to the parent. This has several pleasant effects: any exceptions thrown in the child, including exec() failure, come flying out of start() or run() as though they had ocurred in the parent.

This sounds like what I'm looking for. I'll try it tomorrow and see if lives up to its promises. I would still prefer to do this with a core module if possible and avoid any hassle getting modules installed.

Edit by tye: Remove PRE tags around long lines
