LocalWorkflows should have the option to run tasks in a subshell instead of requiring/yielding them in the same process.

In same cases it could be also beneficial to run branch tasks with a local scheduler.

Mh, just spawning (tons of) subprocesses in the LocalWorkflow's run() method is obviously dangerous. This mechanism should take --workers into account. Sounds ugly.

The implementation might get really dirty. Closing for now.
To force tasks to be run in a new subprocess, one can also use the force_multiprocessing config (spotify/luigi#2401).
