Is it possible to run a shared php-pool while keeping security?

Thank you for your reply. I've set ondemand and pm.start_servers = 0. Now it
works perfectly, but there is a slight delay while the first process starts.
I mean it could be an issue for rarely accessed sites, where the visitors
always have to wait for the php process to start.

Do I feel it right? Is ondemand really slower compared to dynamic for the
first visitor?
