Is there absolutely no way of having webkitgtk-1.4.x (webkit1) and
webkitgtk-1.6.x (webkit2) use the same libjavascriptcore ? Somebody mentioned
that WebCore is tightly integrated with JSC and so it can't be shared when
webkitgtk-1.6.x starts to diverge. That surprises me as right now
libwebkitgtk-3.0 and libwebkit2gtk-3.0 are sharing the same libjavascriptcore,
and all of them are maintaining ABI compatibility. But I don't the internals, so
I could be wrong...

If the ABI needs to be broken, we could still keep the API compatible, just
requiring a rebuild.
