Why not Rails with FastCGI?

When I started using Rails around version 0.9, FastCGI was considered
one of the best ways to deploy Rails. That went out of fashion but I
don't know why. Then Mongrel was the hot thing and I've heard about
Phusion Passenger.

What is wrong with deploying Rails with FastCGI? Was it just some sort
of shared hosting problem?

Is anyone still using FastCGI and having success with Rails?

Thanks.

We always found it a bit flaky (on dedicated hardware). We switched
away from it nearly 4 years ago so I don't really remember the precise
flakiness but I vaguely recall fastcgi dispatches getting wedged and
stuff like that.
