--- Comment #20 from Ere Maijala <ere.maijala at helsinki.fi> ---
Parallel::ForkManager is fine, but I don't think we can make it a required
module just for this, so it needs to be optional. And that would make the
script a bit more complex since it would need to accommodate for both
situations. I'm not sure if it makes sense to have a lot of slice sources since
it may cause concurrency or congestion issues on the MySQL side and there's
perhaps also the possibility of getting connection timeouts since a slice
wouldn't be processed until there are children available. That means I'd rather
change the script so that the main process would only feed children with record
ID's and the children would do all the rest.
