Anyone know of a host with per-second cron jobs?

[Verdagon]

Hey everyone, my friend's dad is looking for a web host that will allow his cron jobs to run every second. Most hosts apparently dont allow cron jobs faster than 5 seconds apart.

How often a host can run cron jobs isn't really advertised on their sites so I'm having a bit of trouble finding a host. I've resorted to just sending emails to sales addresses asking about it.

Does anyone know how I can find a host like this?

Thanks,

- Evan

Is there some reason why you can't use sleep() (http://php.net/sleep) to achieve this goal?
