implies that the summary index and import list generation can be expensive
though which is why this setting is provided. Also some distribution systems
have a mechanism to limit how many processes they launch concurrently on the
local machine - we could pass the parallelization level to the distributors (by
adding it to the JSON) so that this setting may be applied by the distributor?
