Unfortunately integration with other processes does not always lead to the expected results and many tools have been reimplemented in Emacs Lisp to integrate better with the rest of the Emacs platform. Suddenly, not having multi-threading becomes a real issue (Why the heck is Gnus taking so long and why can't I edit in the meanwhile?). Some might say that it is insane to use Emacs for every conceivable task, but it offers me exactly the degree of integration I'm after, a uniform UI and a disruption free environment for most of my computing needs.
