So, there are a few reasons why forkrun might work better than this, depending on the situation:

1. if what you want to run is built to be called from a shell (including multi-step shell functions) and not Go. This is the main appeal of forkrun in my opinion - extreme performance without needing to rewrite anything. 2. if you are running on NUMA hardware. Forkrun deals with NUMA hardware remarkably well - it distributes work between nodes almost perfectly with almost 0 cross-node traffic.
