The way this works is: - Worker creates a tempdir, and sets `tempfile.tempdir` to this directory. - Worker sends back the tempdir. The parent process is responsible for cleaning it up when the worker exits. Abortions are then implemented as sending `SIGKILL` to the worker. As a side benefit of this implementation, we also get to drop the hacky `CompiledExecutor` cache deletion.
