# On macOS, Python 3.8 multiprocessing now defaults to the 'spawn' start
# method. Spack cannot currently handle this, so force the process to start
# using the 'fork' start method.

# TODO: This solution is not ideal, as the 'fork' start method can lead to
# crashes of the subprocess. Figure out how to make 'spawn' work.
