"The new internals will eventually allow for user-space
tasklets or green threads that suspend to a scheduler when they would
cause blocking I/O, allowing users to write straightforward network
services that parse their input and send their output as if it were
blocking, while under the hood Guile can multiplex many active
connections at once."<p>Green threads in the future sounds really interesting. I've never touched scheme (only dabbled in Clojure), but I've always wanted to get a Lisp under my belt. Maybe Guile will be the one, but the biggest issue for me in choosing a Lisp is the sheer amount. It's hard to know the true tradeoffs between different implementations, so maybe I should just go with Common Lisp
