pretty cheap in GHC -- they're not system threads
Am I wrong in this? If so, is this something that might be considered as a future enhancement in the GHC libraries and runtime?
Also, look at STM (e.g. TVars), which is designed to do what you want more directly, I think.
(timeouts might still use the GHC-thread thing. Don't worry about its performance unless you're measurably suffering from it...)
