mod_rails: what MPM model should Apache use?

When using mod_php in Apache 2+ it is important to use the MPM-prefork version of Apache, because some PHP extensions are not thread-safe.

But what about mod_rails? Can it use MPM-worker (multithreading), or does it also need MPM-prefork?

I've read other places, that Rails is not thread-safe. Does this afflict the choice?

At the moment Phusion Passenger only supports the prefork MPM. Later versions will also support the worker MPM. Whether Ruby on Rails is thread-safe is totally irrelevant to Passenger.
