I am using them for testing; although they are not required, they make
testing a complex, asynchronous systems much easier.

My biggest complaint is that they do not work across pcall,
metamethod, and iterator boundaries; I have been bitten by all three. 
There was a proposal a while back to make all Lua core functions
coroutine-safe; this would solve the problem in my case.
