I can bet that running 10 FCGI processes is much lighter on resources  
than running 10 instances of mongrels. what do you think? then why is  
running mongrels is more preferable these days? Is there any work  
going on to make rails thread safe?

We have had far better performance and overall system stability using  
Mongrels over FastCGI processes. If you used something like fcgid or  
one of  
the newer fastcgi implementations its better over mod\_fastcgi, but we  
still  
have found, in several different big apps, that Mongrel is usually  
better  
than FastCGI.
