[_ck_]

Just remember that the cron in bbPress/WordPress is fake and not parallel tasking. Meaning that the user waits while the task is completed when the task is triggered. Unless they are using url fetching via php to do a pseudo multi-task, which I doubt.

Sometimes (most times) a real cron is better. I asked them way-back-when cron was first introduced in WordPress to allow a real cron job to be substituted but still work with the API and I don’t believe they’ve ever done that.
