It all depends on what you are trying to do. The issue that you
originally brought up is that of memory consumption.

When processing data in parallel you will use up as much memory as
many datasets you are processing at any given time. If you need to
reduce memory use then you need to start fewer processes and use some
mechanism to distribute the work on them as they become free. (see
recommendation that uses Queues)
