The main process starts a worker process for each spaCy projects command in the parallel group.
Each spaCy projects command consists of n OS level commands. The worker process starts
subprocesses for these OS level commands in order, and sends status information about their
subprocesses for these OS level commands serially, and sends status information about their
execution back to the main process.
The main process maintains a state machine for each spaCy projects command/worker process. The meaning
