Yesod will definitely work in a non-threaded environment, it just
won't be nearly as scalable. For local development and testing,
however, it should work just fine, and it would even work for moderate
loads in production. Actually, if someone really wanted to, they could
always implement a multi-process system and scale pretty far.
In other words, I think it would still be useful in a non-threaded
environment, but I wouldn't recommend it as my first choice for
deployment.
