Commenting on the approach, rather than your implemenation:
Wouldn't it be cleaner to limit it by load average rather than number of
jobs? This would tend to allow small, one-shot cron entries that really
don't eat a lot of resources to continue running on time, while saving
the machine from the monster processes.
