This is probably not going to come as a surprise to some of you, but
running couchdb with Google's V8 proved to yield less then exciting
results. In fact I didn't observe any significant speed-up during
view creation.
It actually makes perfect sense when we consider the usage pattern:
many eval() statements with (typically) simple functions, not a whole
lot of loops (if at all), and (possibly) objects with many different
internal classes.
