2) As of node 0.6.0, node-fibers is just a module. It never was a
fork, but in node 0.4.0 it was much more of a hack. In node 0.6.0 it
works just like any other module, you install it, require it, and use it.
3) Depending on how you use fibers, it may be possible to rewrite your
code using generators, it may not be. Fibers will give you a superset
of functionality and it's up to you to look at what generators will be
and build your code to support them in the future if that's what you want.
@Marco, notes that I've seen say generators may appear in V8 by end of
2012 - that's too far away for us
@Marcel - thks, our use is mainly for real clean sequencing of
algorithms - so mostly looking at using yield()

fibers and generators (as described in harmony) have a large delta
between them.
if you read the harmony spec for generators you'll notice that the
yield statement pushes it's way all the way up the call stack so
you can't abstract it away the same way common-node does with fibers.
what you should probably do is just use normal node, the way 99%
of the community does :)

1) node will support harmony generators the second they are
stable in v8. The language evolves with v8, node doesn't touch it.
2) To my knowledge, node-fibers is a fork of node with patches to
both node and v8 to enable fibers. So you can't just run node,
you have to run node-fibers.
3) I think it would be very easy to paint yourself into a corner
here. But there are lots of abstractions on top of fibers that
could possibly be implemented later with generators instead. Keep
in mind that when you dig into the details, fibers seem to allow
deeper semantic changes in node than the version of generators in
harmony. I'm not the best person to explain the difference, but
I've understood enough of the talk to know they are not
equivalent paradigms. Generators enable a subset of functionality
that fibers does.
Hope this helps.
