Sounds like you want threads. Spin off a thread that collects data and
sleeps, collects data and sleeps; meanwhile, serve web pages. But
there's no way you can *guarantee* that the serving of pages won't
interrupt data collection. With separate processes, you could
potentially use OS-level prioritization to help your data collection
process, but even then, it's not a guarantee. What are the
consequences of mistimed data collection?
